Matlab compiler c shared library cannot use signal processing toolbox

Hello everyone,

I successfully managed to implement a C shared library under a C# application. Everything seemed to work fine ( I can display plot, do fft calculation, ... ).

Lately I tried to use a basic function of the signal processing toolbox: rms. But. When I want to use it in my C# application, it somehow fails ( the Intprt I return is null and the mlf function return false ). Note that if I compile my algorithm without using the rms function, the C# application does not fails ( the IntPtr I return is not null, and the mfl function return true ). Also the function works fine in Matlab.

The compilation is going fine, but not the implementation. Since rms is a line command function, it is supposed to be compiled and to work fine. I checked that the signal processing toolbox was in the path of matlab. I also tried to compile the library by adding directly rmc.m as "files installed with your application". Unfortunately, nothing work.

So... I may have done something wrong, or have misunderstood something. Can somehow please help me to solve it? Note that the problem is not really about the implementation of rms ( I know that re-doing rms myself should not be too muck work.. ), but about the fact the using a function of the signal processing toolbox make my application somehow fails.

Thanks you in advance.
