C++ 尝试编译多个c++；MATLAB的mex文件

我正在Ubuntu下使用MATLAB，想用mex编译一组带有头文件的2个c++文件。我展示了一个基本的例子和我得到的错误

这个代码从C++函数中产生文本“hello”，从MeXFECT开始，用Max（MeX MpExyAlx.CPP）在Matlab中编译：

然后是新函数的文件

try.cpp

：

#include <mex.h>
#include <iostream>
#include <try.h>
using namespace std;

void newfunc(){
    cout<<"hello\n";   
}

使用

-I

选项的另一次尝试：

>> mex  -I mexTryAlex.cpp try.cpp try.h

     currently supported with MEX is "4.3.4".

如何编译这些文件？

该错误已通过使用修复

#include "try.h"

而不是

 #include <try.h>  

#包括

在源文件中

只是一个一般性的建议：

使用名称空间std不是最好的想法。只需使用
std:：cout
，或者如果你经常使用
cout
并想将其缩写，请使用
使用std:：cout，但从长远来看，打开整个std名称空间会让你头疼：）看看这里，了解关于这个主题的利弊/讨论。
