This occurs when building the 3.0-ocl-tp2 tag as well as well as currentmaster (f104d5be8cf54d11b0fcfaf4c891a). I am currently able to linkthe 2.4.8 release framework without issue.
(note: this shouldn't be relevant but I did have to apply the workaround fromin order to build opencv2.framework)

In addition, I modified the cmake files to export every symbol by removing -fvisibility-inlines-hidden and changing -fvisibility=hidden to -fvisibility=default. This did not work unfortunately.

I'll give a look in these days, but i can't assign the bug to myself, maybe because it's open in master branch.send me an example xcode project ( i'm using latest xcode, 5.1 ), and i'll try and see what is the problem
Updated by
Thanks Alessandro.
I will put together an XCode project (note: I'm still on 5.0.2 but shouldn't be an issue).
One other data point however. This seems to come down to non-trivial use of std:vector !
for example this links fine:
void foo(Mat image) {
vector&vector&Point& >
cout << contours.size();
Canny(image, image, 10, 20, 3);
//findContours(image, contours, RETR_LIST, CHAIN_APPROX_SIMPLE);}
If you uncomment the call to findContours above you get:

Ok.you can link against several versions of stl, with little differences, maybe you are using the wrong one ( i'll check in your project );while xcode 5.1 has some additional issues that i'm fixing with another ticket ( but it's working now on my laptop, and i will submit PR asap )
Updated by
:/ Initially, it appears the above testcase isn't an issue with a minimal project. Once I can sort out the issue with my own project I will post more details and (hopefully) cancel this ticket.
Updated by
I resolved this by deleting all frameworks from all targets in my proect and re-adding. Excuse the noise but thanks for your help Alessandro.Status changed from New to Cancelled

Maybe was related to framework order in your xcode project, then.

I have just started using OpenCV2 as a framework for iOS development since last week (although I have been using OpenCV libraries for about a year). I have encountered this very error regarding undefined symbols of getMatVector and getMatUVector:
Undefined symbols for architecture arm64:"cv::_InputArray::getMatVector(std::vector&cv::Mat, std::allocator&cv::Mat& >&) const", referenced from:vtable for cv::_InputOutputArray in openCVUtils.o"cv::_InputArray::getUMatVector(std::vector&cv::UMat, std::allocator&cv::UMat& >&) const", referenced from:vtable for cv::_InputOutputArray in openCVUtils.old: symbol(s) not found for architecture arm64clang: error: linker command failed with exit code 1 (use -v to see invocation)
I am building OpenCV2 framework based on the tutorial given on the documentation
on OS X Mavericks 10.9 and my deployment target is iOS 6.1. My experience with the installation went smoothly without the workaround mentioned above. Furthermore, I tried creating a separating, smaller iOS Xcode project that used the same portion of OpenCV code (K-means Clustering, specifically), and I was able to compile and run the project without issues. On the other hand, my bigger iOS project ran into these undefined symbols error. Commenting out the same portion of code did not produce the error.
I also tried deleting all frameworks and re-adding them, but did not work. Any help is really appreciated. Thank you!Status changed from Cancelled to Open
Updated by
Cancelled again since I found a way to resolve this issue, and it does not really have to do with OpenCV2 framework itself. However, I would like to share what I found that helps me resolve it, and you can find it .Status changed from Open to Cancelled

Your terminology confuses me. What is &a mat file like this& exactly, and what are a b and c?
Anyways, what have you done so far and where do you get stuck?

Refering to my question above, i have an ecg data in .mat file. The .mat file contains 5 different data. How do i load 1 of 5 data in a time. Is it possible to load 2 data in a time?
Once you load a mat file, all 5 types of data get loaded. Therefore, your question is not very clear.

Did you read the help on load()?
&S =3D load(filename, variables) loads the specified variables&
so you'd do something like (untested)
storedStructure =3D load(matFullFileName, 'yourEcgSignal',
'yourIntegerVariable', 'v1', v2', 'v3');
If you want separate variables instead of members of a single
structure, you'd do:
yourEcgSignal =3D storedStructure.yourEcgS

...Hi all,
I'm having trouble saving a MATLAB file. After running my code, all of the following save attempts fail with the same error:
&& save(['Out/love.mat'],'C')
??? Index exceeds matrix dimensions.
&& save(['love.mat'],'C')
??? Index exceeds matrix dimensions.
&& save(['whymatlab.mat'],'C')
??? Index exceeds matrix dimensions.
&& save(['whymatlab'],'C')
??? Index exceeds matrix dimensions.
I've included multiple attempts and the variable to show that it's not, e.g., that the folder &Out& does not exist.
It's not my computer, either, since
&& C = 16;
&& save(['whymatlab'],'C')
works fine.
For what it's worth, the relevant line in the code gets the orange flag: &the operation or expression &Indexing& has no evident effect&
I'll include any code as per request, but I really have no idea what's relevant.
Thanks for all the help!
Found the error. No further help required. Thank you.

There is a problem with the file. I get a &Can't read file&
type of error when I try to load it.
If the file was written from a Solaris system in 1997, all kinds
of problems regarding binary formatting, particularly endian-ness,
could be the cause. On the other hand, I can't remember having
had any problems porting .mat files between platforms in those days?
Could it be that recent versions of LOAD no longer support
arbitrary endian-ness .mat formats?
You could check this by trying to load with an old (v5.x or v6.x)
version of matlab, if you have one.
thanx for ur reply.
sir can u suggest us any links for similar kind of programs(digit recognition through speech processing using danauchies wavelets)

I am dealing with raw data files coming from RDI oceanographic instruments. They have an extension .000 (binary file). I will need to convert them into .mat files.
I know that Nortek has developped a tool named bin2mat, which converts their raw data files (.aqd, .adp,...) into .mat files, is there any similar tool for RDI instruments?

...I'm writing a program at the moment, but it involves alot of numbers and so when it runs it gets progressively slower. There is a main for loop in the program and I want it to save the variables it calculates to a file. I have tried using the 'save' function with the append option, but that doesn't quite do what I want.
In my program I end up generating quite large arrays and I want to save them, but if I call:
save('data_out.mat', 'big_array', '-append');
Then each time it is called it will overwrite the previous 'big_array', when instead I want it to save 'on top' of the previous big_array variable. This way, at a later point I could simply use the load command to load the file into RAM and access 'big_array' after each iteration.
I did think that I could do it by taking the old 'big_array' variable and combining it with the new 'big_array' to get a third array which can then be written to disk.
new_array = [big_array big_array_new];
save('data_out.mat', ...);
The problem with this technique is that (a) it takes time because of the load function call necessary to get the old data, and (b) combines the old and new data on the RAM and so doesn't increase speed of execution. In fact, I think it might even be slower because I think it would copy the old data and new data into a separate new array - making the problem of slow computation even worse.
There ...I have MS Visual C++ 2005 and 2008 installed in my machine as well as windows 7. Using deplytool (and by choosing a sand-alone windows application) I created a compiled (*.exe) stand-alone file. Everything was going well with no error. But when I want to run the *.exe file, I get the following error:
An application has made an attempt to load the C runtime library incorrectly.
Please contact the application's support team for more information.”
I check and did the following solution from mathworks:
/support/solutions/en/data/1-6GDQZ6/index.html?product=CO&solution=1-6GDQZ6
but it didn’t work.
I also checked several other suggestions through the internet but they are so confusing and sometimes complicated and no use.
Anyone has idea how to solve this problem? I am really surprised how such simple and important things could be a big problem in matlab.

I'm not sure I understand your question.
*.mat files are used to store variables that you have created. These can be read in Matlab in the command line and simultaneously assigned to a structure variable, for example, with: var_name=open('name_of_file.mat')*.m
They cannot directly be read as a worksheet in spreadsheet programs, although the data can be exported to a compatible format or written, for example, with xlswrite.
*.m files are used to store instructions for programs that either you or someone else has written.

--------------------------------------
Your series was
f(t) = 1 + 4/pi sum_{n=0}^infty (-1)^(n+1)/(2n+1) cos((2n+1) pi t/2)
Note that cos((2n+1) pi t/2) = Re exp((2n+1) pi i t/2).
So let's find
sum_{n=0}^infty (-1)^(n+1)/(2n+1) exp((2n+1) pi i t/2).
This is g(w) = sum_{n=0}^infty (-1)^(n+1) w^(2n+1)/(2n+1) where
w = exp(pi i t/2).

I have recently installed Matlab 7.0.
I have save my simulation results in .MAT file.
However, these MAT files can't be opened using Matlab 6.5.1.
I encountered problem as follows:
??? Error using ==& load
Unable to read MAT file D:\MATLAB7\work\results.mat
File may be corrupt.
How can I solve this problem?
Please see here:
&http://tx.technion.ac.il/~perryb/matlab7/mat7.pdf&
In short, save again as:
The new features and enhancements are described in the &Release
notes& of Matlab. A
new feature that causes incompatibility with previous versions of
Matlab is the new
encoding of MAT files.
Matlab release 14 writes character and figure data to MAT-files using
Unicode encoding
by default. Unicode encoded MAT-files are not readable by earlier
versions of Matlab. If
you intend to load your MAT-files created with Matlab release 14, you
must override the
Unicode default during the save.
You can override the default encoding by using the -v6 switch with
save and hgsave:
save filename -v6
hgsave filename -v6
Hope it helps

I have an array 1-D of 20 shared variable and I want to export their value in a file in exel format as follow:
NAME&& 1th Variable&&&&&&&&&&&&&&&&&&&&&&&& name 2th variable&&&&&&&&&&&&&& name 3th variable&&&&&&&&&&&&&&& ......
&&&&&&&& 14&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& 2&&&&&&&&&&&&&&& ...hi all,
I'm using the VB macro from the Word document. I'm able to print my
output into the direct window of the macro by using the command
&Debug.Print x&. so this puts the contents of the the variable x into
the direct window. but the problem is if there is too much of data
then I cudn't see all of the data saved in this direct window, as it
is getting truncated at the end of the application.
so cud anyone pls tell me how to divert my output into the active word
dcoument instead of the active direct window of the macro.
does anyone know why Fortran-mex files can't be compiled on matlab
V5.3 and run on matlab V6?
For example: if I compile the example-program (shipped with matlab)
timestwo.f
on matlab version 5.3 (R11) and try to run
it on matlab version 6+ (R12 or R13), I get the error message:
&Unable to load mex file: E:\timestwo.dll. The specified module could
not be found.
??? Invalid MEX-file&
Likewise if I compile it on matlab version 6.1 (R12), I get a similar
error message if run on matlab version 5.3 (R11).
However, if I run it on matlab version 6.5 it works OK.
If I try the same experiment with the corresponding example file
written in C, timestwo.c, I get no such problems.
Why is that?
usually MEX-files need to be compiled with the MATLAB version you
want it later to run with. The reason is, that the code links against the
dynamic libraries (DLLs), which may change from version to version.
You may have luck that it works (see your example of timestwo.f),
but you should never rely on this.

??? Error while evaluating TimerFcn for timer 'Scheduler_timer'
Error using ==& load
Unable to read MAT-file D:\Scheduler\Scheduler.mat: not a binary MAT-file.
Try LOAD -ASCII to read as text.
For a little more background.
I am developing 2 GUIs that are being compiled using deploytool on a Vista home premium machine running matlab 2007a and testing on a xp pro machine without matlab installed.
There are two GUIs that each have multiple timers with TimerFcns that load and save to a single shared .mat file.
When I run both GUIs at the same time inside matlab, I have no problems, but when I compile the two GUIs independently and run them, then I get this error.
Is there some kind of file I/O error with reading / writing simultaneously that is otherwise handled inside matlab?
I haven't found any kind of isopen function to check to see if a .mat file is already being saved or loaded to avoid a conflict.
Any advice?

I’m trying to import historical prices of stock data. Matlab keeps cutting off the h it gives me only values. I am thinking that this is a data-type-mixing-issue, or whatever it’s called.
I have ‘Dates’ in ColumnA, and ‘MSFT’, ‘PWER’, ‘KO’, and ‘SBUX’, in ColumnB-ColumnE.
Basically, if I put the Excel file in my Matlab folder and double-click the file, I see the values in a matrix (no dates and no headers), I hit ‘Next’. Then, I one radio button is enabled – ‘Create variable matching preview’. The other two options, ‘Create vectors from each column using column names’ and ‘Create vectors from each row using row names’ – both are greyed out. I’ve seen videos, on YouTube and on the Matlab site, where people import excel data and these options are NOT greyed out. No matter what I do, there options are ALWAYS greyed out. The problem is, when I click ‘Finish’ in my ‘Workspace’ I have a variable named ‘data’ all values in a 575x4 matrix, but I have NO DATES and I have NO HEADERS on the columns. All of this seems to go into another variable, called ‘textdata’; all dates and headers ate in textdata. This is VERY inconvenient. I’m trying to
analyze some stock data and I have no headers, so I have no idea which stock is which (I can figure it out, but I think Matlab should do this for me). Also, I have no dates corresponding to ...I would like to plott data from a text file in the same way as a media player does from a video file. I?m not sure how to create the pointer slide function.

HI Martin,
i am not realy sure what you want!?!?
i think you want to display only a part of the values you read from XYZ
so what you can do:
write all the values in an array.
the size of the array is the max. value of the slide bar
now you can select a part of the array (e.g. values from 100 to 200) and display this with a graph
the other option is to use the history function of the graphes
I will try your suggestion.
Many tanks!
