Sorry, I wrote the question bad, as you said I would want to control a multiplication of each element of the matrix (not a "classical" mathematical matrix multiplication)

And Yes, I knew that I can control the situation but I wanted to know if it is possible to work in the same way like Matlab ...

Thanks
