MATLAB调用Ｃ＋＋算法的疑问

leftfullba

<P>在ＭＡＴＬＡＢ下调用Ｃ＋＋编写的程序，系统有如下的警告：<BR>&gt;&gt; mex testm.cpp<BR>testm.cpp <BR>D:\Microsoft Visual Studio\VC98\INCLUDE\istream(547) : warning C4530: C++ exception handler used, but unwind semantics are not enabled. Specify -GX <BR>D:\Microsoft Visual Studio\VC98\INCLUDE\complex(203) : warning C4275: non dll-interface class 'std::_Complex_base&lt;float&gt;' used as base for dll-interface class 'std::complex&lt;float&gt;' <BR>        D:\Microsoft Visual Studio\VC98\INCLUDE\complex(203) : see declaration of 'complex&lt;float&gt;' <BR>D:\Microsoft Visual Studio\VC98\INCLUDE\complex(216) : warning C4275: non dll-interface class 'std::_Complex_base&lt;double&gt;' used as base for dll-interface class 'std::complex&lt;double&gt;' <BR>        D:\Microsoft Visual Studio\VC98\INCLUDE\complex(216) : see declaration of 'complex&lt;double&gt;' <BR>D:\Microsoft Visual Studio\VC98\INCLUDE\complex(229) : warning C4275: non dll-interface class 'std::_Complex_base&lt;long double&gt;' used as base for dll-interface class 'std::complex&lt;long double&gt;' <BR>        D:\Microsoft Visual Studio\VC98\INCLUDE\complex(229) : see declaration of 'complex&lt;long double&gt;' </P>
<P><BR>不知道这样的警告是不是就不可以调用该算法，请问有和改进方法？？？<BR>程序编译可以生成．ＤＬＬ文件，但是调用的结果不正确．<BR>谢谢</P>

<P>我只用mex编译过c.你先找一下matlab有没有自带的c++程序，编译一下看是否正确。</P>

<DIV class=tc>这是因为使用了C++异常。/EHsc或/GX,两者是等价的。<BR><BR>exception. It is equivalent to /EHsc.<BR><BR>/GX is in effect, by default, when you compile from within the development environment. By default, /GX- is enabled when using command-line tools.<BR><BR>For more information, see C++ Exception Handling.<BR><BR>To set this compiler option in the Visual Studio development environment <BR><BR>Open the project's Property Pages dialog box. For details, see Setting Visual C++ Project Properties. <BR>Click the C/C++ folder. <BR>Click the Command Line property page. <BR>Type the compiler option in the Additional Options box. </DIV>
