已从链接上下载到libsvm-mat-2.89-3，谢谢！指定自带编译器1，工作目录也确实对的，(我把该工具箱解压缩放到toolbox下面，用了setpath了，也改了工作路径了)，仍然报错，全文如下：

>> 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] Lcc C version 2.4.1 in D:\PROGRAM FILES\MATLAB71\sys\lcc

[0] None

Compiler: 1

Please verify your choices:

Compiler: Lcc C 2.4.1

Location: D:\PROGRAM FILES\MATLAB71\sys\lcc

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

Try to update options file: C:\Documents and Settings\Administrator.F0D93FC350FB4E0\Application Data\MathWorks\MATLAB\R14SP3\mexopts.bat

From template:              D:\PROGRAM FILES\MATLAB71\BIN\win32\mexopts\lccopts.bat

Done . . .

不知何故！

我想就听从版主意见下个VC吧(我的笔记本老了，只有60G的硬盘，所以我是程序能不装就不装的)，谁知下到的VC++ 6解了压缩是Microsoft Visual Studio，一头雾水。。。

如何是好？
