本人在Matlab环境中配置VC++编译器时，mex –setup和cd(prefdir)命令都能运行，但输入mccsavepath命令后Matlab提示找不到这个函数，这是为什么呢？而且mex –setup运行后也不是显示“Installing the MATLAB Visual Studio add-in……”的信息，而是如下：
>> mex -setup

Please choose your compiler for building external interface (MEX) files:

Would you like mex to locate installed compilers [y]/n? y

Select a compiler:

[1] Digital Visual Fortran version 6.0 in C:\Program Files\Microsoft Visual Studio

[2] Lcc C version 2.4 in E:\MATLAB701\sys\lcc

[3] Microsoft Visual C/C++ version 6.0 in C:\Program Files\Microsoft Visual Studio

[0] None

Compiler: 3

Please verify your choices:

Compiler: Microsoft Visual C/C++ 6.0

Location: C:\Program Files\Microsoft Visual Studio

Are these correct?([y]/n): y

Try to update options file: C:\Documents and Settings\kke\Application Data\MathWorks\MATLAB\R14\mexopts.bat

From template: E:\MATLAB701\BIN\WIN32\mexopts\msvc60opts.bat

Done . . .

>> cd(prefdir)

>> mccsavepath

??? Undefined function or variable 'mccsavepath'.

这又是为什么呢？请各位帮帮忙，谢谢大家！
