有一段C++写的Mex程序，编译通不过。找不出来原因，非常沮丧(说实话，我最怕就是把书上的码敲进去编译通不过了，感觉是自己犯了很低级的错误...)
大家帮忙看一下吧 谢谢了

What's the error message?

How did you compile the mex file (the complete command you ran in matlab)?

Which compiler you used when you "mex -setup"?

Which version of matlab are you using?

错误信息很多，所以没贴上来。我贴在下面吧。

mex diffComplex.cpp
Which compiler you used when you "mex -setup"?
VC 6.0
Which version of matlab are you using?
7.3.0(R2006b)

大 ...

typedef std::vector<std::complex<double>> cmplxArray;

请注意看你的程序中这行中红色、粗体的那两个“>"号，C++语言中“>>"是一个有效的操作符，而在我们的程序中，应该用空格隔开那两个“>“括号。这在编写C++程序尤其是使用模板的时候需要特别注意。

附件是我用的例子。不好意思，回复地有点晚了。

已经很及时了 您太客气了...  非常感谢！！
要不是您指出，这错误我怎么找也找不出来的.... :)  再次感谢...
