I have a .dll library (c++) and I need to Import it to Matlab (I have no header file for it)

loadlibrary() doesn't work with me because i have no Header file

You will need to write a header file for it listing all the interface routines you wish to be able to call.

Note: it will only be possible to call functions which were created with

   extern "C"

in the C++ source.

I have got this Header file but when i load it it finds no functions : link http://www.turbolab.de/mdf_libf.htm

[Walter Roberson]

That project indicates that it supports COM interface, so you could use actxserver() to access the facilities.

[Omar Abdelkader]

yes it's a valid Option but the Problem is that I need to register the dll file first which needs admin. rights and I need to run the program for other users that don't have admin. rights

Exactly which of the several packages on that site are you using? mdf4reader ?

[Walter Roberson]

Looking at the code, it appears to me that it is not designed to be called from C, but

"The loadlibrary function only supports calling functions that are callable from C and header files that can be parsed by a C compiler. Functions written in C++ must be declared as extern "C"."

To call it from MATLAB, you would have to create some interface code that was C compatible.

yes I'm trying to use mdf4reader, I tried to add extern "C" to the 'CMdf4Reader.h' code, I get a warning that there were no functions found!
