Call MATLAB-created DLL

Hi,

I'm trying to call a MATLAB created DLL-File in MATLAB but the result is not as expected. I found ot that I have to pass 4 arguments to adress the function but still something is wrong? Following code demonstrates the complete process:

%% Function File

% function OUTPUT = FlipMyString(INPUT)

% OUTPUT = fliplr(INPUT);

%% Call-Test of Function

OUTPUT = FlipMyString('TESTSTRING');

%% Create DLL

mcc -g -v -W cpplib:libFlipMyString -T link:lib FlipMyString

%% Call Library

LIBRARY = 'libFlipMyString';

if ~libisloaded(LIBRARY)

   loadlibrary(LIBRARY)

end

LIB = libfunctions(LIBRARY);

[A,B,C] = calllib(LIBRARY,LIB{end},1,'teststring',1,'TESTSTRING')

%% Unload Library

unloadlibrary(LIBRARY)

The library (.dll) created using MATLAB cannot be loaded into another MATLAB. A DLL generated by MATLAB Compiler SDK is intended to be used by other applications rather than using it back in MATLAB.

If you would like to share your program with other users who may or may not have MATLAB, you can create an executable using MATLAB Compiler. And, this can be executed in MATLAB using bang operator (!) or System command or from Windows command prompt.
