在MATLAB中键入mex -setup，出现由于MATLAB版本过低而找不到相应的VS的情况。比如我的只找到了VS2010。总不可能再下载一个VS2010或者新版MATLAB吧。。。
我的MATLAB版本为2011b，只能搜到VS2010。这种情况下，去官网下载文件：
http://www.mathworks.com/matlabcentral/fileexchange/44408-matlab-mex-support-for-visual-studio-2013–and-mbuild-
按照readme中的要求复制文件即可。当然相应的路径设置成你自己的。
官网上的MATLAB版本是R2013a，但是我在自己的Matlab 2011b上试也成功了。
文件都复制完后在MATLAB中键入mex -setup
>> mex -setup

Please select from 0-14
Compiler: 14选择VS2013
然后后面的检查路径正确都是yes就好了。
以后进入时
>> mex -setup
