connecting matlab to c language dll

[mahnaz0098]

hello
i'm trying to use clllib function in matlab i put .dll file and .h file in the same directory as the .m MATLAB file being developed and after that i try to use loadlibrary function but it have some warnings:

>> loadlibrary('t1.dll', 'T1Header.h')
Warning: Message from C preprocessor:
lcc preprocessor warning: C:\Users\MAHNAZ\Documents\MATLAB\T1Header.h:21 No newline at end of
file

> In loadlibrary at 351
Warning: The function 'Add' was not found in the library
> In loadlibrary at 435
Warning: The function 'Function' was not found in the library
> In loadlibrary at 435

when I want to use the calllib function like this: calllib('t1', 'Add', 2,3) matlab gives me an error:

??? Error using ==> calllib
Method was not found.


my header file is:

#ifndef _T1_HEADER_H_
#define _T1_HEADER_H_
 extern "C"
{
 int Add( int a, int b );   
 void Function( void );
 }
#endif

my source file is:

#include <stdio.h>
#include "T1Header.h"
 extern "C"
 {
	int Add( int a, int b )
   {
      return( a + b );
   }

	 void Function( void )
   {
	   printf("DLL Called.\n");
   }

 }

I use visual c++ 2010 and Matlab 7.6.0(R2008a)

Any suggestions on what is wrong, what I could do to fix this error, or what else I could try to call this .dll from within MATLAB?

To get rid of warnings, add a new blank line at the end of file.

If you're using the MS compiler, use Visual studio to create your DLL. It adds quite a few extra bits like exports, which are missing from your code
