    trying to return an array of floats

    float& GetMatrix(IModel* model)
    {
    float matrix[4][4]; //// not my code
    model->GetMatrix( &matrix[0][0] ); // not my code

    return &matrix;

    }


    ok , im working with an engine and the float matrix[4][4] and model line are what needed to get the array .

    but how do i return it, cant figure out how..

    You can't return an array from a function. The usual method is to pass the array in and work with it that way.

    another option would be to create a class called Matrix, perhaps even a template class, with integers as template parameters to define the size of the matrix at compile time. then you could overload some operators to make it (mostly) transparent to the caller. this is what I would do in your situation.
