Select a compiler:
[1] Digital Visual Fortran version 6.0 in C:\Program Files\Microsoft Visual Studio
[2] Lcc C version 2.4.1 in D:\SOFTWARE\MATLAB\sys\lcc
[3] Microsoft Visual C/C++ version 6.0 in d:\software\C_installer
[0] None
Compiler: 3
Please verify your choices:
Compiler: Microsoft Visual C/C++ 6.0
Location: d:\software\C_installer
Are these correct?([y]/n):

Warning: Mex requires that the Microsoft Visual C++ 6.0
directories "VC98" and "Common" be located within the same parent directory.
(Expected to find a directory named "Common" in the directory 'd:\software\C_installer'.)   强烈怀疑是安装vc++时候,文件夹不统一,这个可能会造成一些问题..





显然,自己没有安装vc98

Try to update options file: C:\Documents and Settings\Administrator\Application Data\MathWorks\MATLAB\R14SP3\mexopts.bat
From template:              D:\SOFTWARE\MATLAB\BIN\win32\mexopts\msvc60opts.bat
Done . . .

  Warning: The file extension of 32-bit Windows MEX-files was changed
           from ".dll" to ".mexw32" in MATLAB 7.1 (R14SP3). The generated 
           MEX-file will not be found by MATLAB versions prior to 7.1.
           Use the -output option with the ".dll" file extension to
           generate a MEX-file that can be called in previous versions.
