How to use generated matlab code (.h .dll .lib) in c++ program

[EDIT: 20110608 10:06 CDT - reformat - WDR]

Dear All,

I wrote a function in matlab which multiply 3 by the input. And I have compiled it to .h .dll and .lib. Is there any tutorial about how to write code in C++ side?

This is my code:

#include <stdio.h>
#include "C:/Users/Administrator/Documents/MATLAB/test1/Untitled1/distrib/Untitled1.h"
#pragma comment( lib, "C:/Users/Administrator/Documents/MATLAB/test1/Untitled1/distrib/Untitled1.lib" )

int main()
{
  double r[4] = {1,2,3,4};
  double res[4];
  mwArray a(1,1,mxDOUBLE_CLASS);
  mwArray b(1,1,mxDOUBLE_CLASS);
  a.SetData(r,4);
  test(1,a,b);
  b.GetData(res,4);
  
  return 0;
}
