MATLAB7.0中设置mex -setup有关问题

MATLAB7.0中设置mex -setup问题
我要用mcc命令，必须要设置mex   -setup我在MATLAB6.5中可以设置，可是在MATLAB7.0种老是出现问题，具体操作结果如下  
> >   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   C:\MATLAB7\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\dayan\Application   Data\MathWorks\MATLAB\R14\mexopts.bat  
From   template:   C:\MATLAB7\BIN\WIN32\mexopts\msvc60opts.bat  

Done   .   .   .  

> >   cd(prefdir);  
> >   mccsavepath;  
???   Undefined   function   or   variable   'mccsavepath '.  
设置mex   -setup时保存路径出现错误，是不是7.0版本中不能用mccsavepath命令啊？？
而在MATLAB6.5中就可以，操作结果如下
  mex   -setup
