mwArray crashing in c++ code

hi,

 i have complied a matlab function to c++ function using mcc. 
 the resulting c++ function needs mwArray's as input.
 in my c++ code when i specify
 mwArray output_results(1,1,mxDOUBLE_CLASS);

 the code crashes. Anywhere I try to define a mwArray the code crashes.

 What should i do to resolve this.

 thanks in advance

You probably are missing a call to mclInitializeApplication. Please follow the example from the documentation to ensure that you perform all the required steps.

Had the same problem. Anywhere I declare a mwArray objet it crashes. Even after mclInitilizeApplication.

I'd like some comments on the issue.

[Kaustubha Govind]

Do you also have the following lines after the call to mclInitializeApplication:

if (!libmatrixInitialize()){
        fprintf(stderr,"could not initialize the library 
                        properly\n");
        return -1;
}

[Bruno]

Yes I do.

here is my code :

    mclmcrInitialize();
    if (mclInitializeApplication(NULL, 0))
    {
       if (MyLibInitialize())
       {
          mwArray plugin;   <=== crash
          ...
       }
    }

Hmm.. I haven't used MATLAB Compiler in a while, so I might be missing something. Could you perhaps try the example in the documentation and see if that works? If it does, perhaps you should try to emulate the example more closely to see if that works better.

The documentation that you linked is no longer available on the Mathworks site.
