Re: PMMatrix vs Matrix

Yes this what I was going to answer as well. Matrix in Pharo does not
implement the usual mathematical operators like PMMatrix.
Maybe should be rename as Array2D in order to avoid confusion in the future.

Re: PMMatrix vs Matrix

I have been working on Grid in the context of the Container library.

Now Array2d was the previous name of Matrix so let us keep it simple.
