解决Win8.1+Matlab2012b运行mex -setup出现perl command line interpreter has stopped working

解决方法：

perl command line interpreter has stopped working

C:\Program Files\MATLAB\R2012b\sys\perl路径下的release文件指出，active版本只能支持到win7.

于是下载最新版本的activeperl。安装在任意目录下。

在安装目录中，找到其中和C:\Program Files\MATLAB\R2012b\sys\perl\win32目录中bin,etc,lib,site中对应的文件，

复制粘贴，选择全部替换，运行mex -setup不会再出现。perl 的问题了。
