MATLAB中mcc验证出错！

我安装好MATLAB后验证mex成功mbuild成功就是mcc失败是怎么回事？出错内容如下>> mcc -p my_hello.m
??? Error: No source files were specified (-? for help).
>> mcc -x my_yprime_m
??? Error: -x is no longer supported. The MATLAB Compiler no longer generates
MEX files because there is no longer any performance advantage to doing so: the
MATLAB JIT accelerates M-files by default.
To hide proprietary algorithms, use the PCODE function.
请高手帮忙分析一下 谢谢了
但是>> mcc -m my_hello.m

To get started, type one of these: helpwin, helpdesk, or demo.
For product information, visit www.mathworks.com. 这个却成功了 这是怎么回事？

这是因为你的mcc过期了，在命令窗口可以输！mcc查看。

去matlab论坛看下吧~这个问题目前真没有确切的解决办法~
