在Matlab中构建C mex文件时出错:权限被拒绝

我试图在matlab中编译C代码.

I have tried to compile C code in matlab.

我用matlabroot/extern/examples子文件夹中的简单示例代码进行了测试.我做了以下事情:

I tested with the simple example code in the matlabroot/extern/examples subfolders. I did the following:

mex -setup
copyfile(fullfile(matlabroot,'extern','examples','mex', 'yprime.c'), './');
mex -v -g yprime.c

命令行输出以下信息，我认为应该是路径问题，但我不知道如何解决.

The command line outputs the following information, which I guess should be a path problem, but I don't know how to solve it.
