[x]=function 文件名(a)
end
的形式
如再将.m文件生成.dll文件
matlab6.5下生成动态链接库命令
mex -setup
mbuild -setup
mcc -t -h -L C -W lib:sy -T link:lib 文件名.m
再在VC里调用
// zzDlg.cpp : implementation file
//
#include "stdafx.h"
#include "zz.h"
#include "zzDlg.h"
#include "sy.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;

}追问我的输入参数为CString类型应该怎么办??
追答转成int型的

VC代码：
char* pszFileName="C: \\myfile.txt";
CStdioFile myFile;
CFileException fileException;
if(myFile.Open(pszFileName,CFile::typeText|CFile::modeCreate|CFile::modeReadWrite),&fileException)
{
myFile.WriteString("第1行\n");
CString strOrder;
strOrder.Format("%d,%.3f",66,88.88);
myFile.WriteString(strOrder);
}
else
{
TRACE("Can't open file %s,error=%u\n",pszFileName,fileException.m_cause);
}
M文件读文本文件代码：
>> fid1=fopen('d:\char1.txt','rt');
>> b=fscanf(fid1,'%s')
然后将M文件生成dll文件，VC调用dll文件。
具体过程百度文库里就有

为了在mex函数里调用Matlab命令，我们就需要用到一个函数mexCallMATLAB，原型如下：
int mexCallMATLAB(int nlhs, mxArray *plhs[], int nrhs, mxArray *prhs[], const char name);
#include "mex.h"
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
double *inData;
mxArray *IN[1];
mxArray *OUT[1];
double *outData;
int M,N;
int i,j;
//异常处理
if(nrhs!=1)
mexErrMsgTxt("USAGE: b=rot(a)\n");
if(!mxIsDouble(prhs[0]))
mexErrMsgTxt("the Input Matrix must be double!\n");
//计算转置
if(mexCallMATLAB(1,OUT,1,prhs,"'"))
mexErrMsgTxt("Error when compute!\n");
//根据输入参数数目决定是否显示
if(nlhs==0)
mexCallMATLAB(0,IN,1,OUT,"disp");
else
plhs[0]=OUT[0];
}
关于这个例子，相信一看就明白，我就不多说了追问初学，不太明白，假如我的M文件为file.m，而且有输入，那么应该如何编写，能给点详细的步骤吗？谢谢了！！

教得很详细
