A*=|A|A逆|A|=1*2*(-3)=-6记φ(A) =A*+3A+2E则φ(A)的特征值φ(λ) =|A|/λ+3λ+2=-6/λ+3λ+2代入λ=1,2,-3得-1,5,-5所以|A*+3A+2E|=（-1）*5*（-5）=25&&方法：若λ是A的一个特征值,则φ(λ) =a0+a1λ+ … +amλ^m是矩阵多项式φ(A) =a0E+a1A+ … +amA^m的特征值如图：iOS 问题：CoreLocation.framework和QuartzCore.framework等都添加，.mm文件也改了几个，-all_load,
$(SRCROOT)/libs/Release$(EFFECTIVE_PLATFORM_NAME)路径也放上去，，现在出现这个问题，，搞了好几天都木有解决哦，，大神们可以帮帮忙看看嘛？哪里出现问题了

重启软件就可以了，多多少少都会发生这个情况，不要太见怪，如果是经常出现这个问题，那就有问题了
我重启了N次
每次都这样
