I'm trying to create a DLL with Visual Studio, and then i'd like to use it in Matlab using the "loadlibrary('xxx.dll','xxx.h')".

The Dll seems correctly compiled in Visual Studio, and when i use the loadlibrary of Matlab, on the "command windows" nothing error appear.

But, when i call the function defined in the Dll, the error "??? Undefined command/function 'somma_init'.", has shown

Can you help me about this point?, I can share the code of Dll written in Visual studio.

thanks.

I think you need to use the calllib function to invoke the function:

Thanks so much Ryan, with use of Calllib function it work fine.

But now i have another problem with use of "libpointer".

I want that my DLL return an array of numbers for example:

Test=[12,32,1,54];

i tried to use the libpointer, but the return of DLL is a libpointer empty.

Can you give me e suggestion?

thanks
