If I execute the following example code, it will print False Not enough input arguments.. If I include the save(...) command for debugging purposes and load debug_dump.mat afterwards, it only holds a single variable called a with size 10x10x3.

Is there a flaw in my code that I am not able to spot or is this problem rooted somewhere in the pymatbridge package? I am using pymatbridge 0.6.0-dev with Python 2.7.9 and Matlab R2014a.

def test():
    dummy1 = np.random.normal(size=(10, 10))
    dummy2 = np.random.normal(size=(10, 10))
    dummy3 = np.random.normal(size=(10, 10))

    mlab = Matlab()
    mlab.start()
    returnval = mlab.run_func('multiply_them.m', dummy1, dummy2, dummy3, nargout=1)
    mlab.stop()

    print returnval['success'], returnval['content']['stdout']

if __name__ == '__main__':
    test()

The matlab function stored in multiply_them.m:

function d = multiply_them(a, b, c)
    % save('debug_dump') % store all known variables in workspace
    d = a*b*c;
end
