So do I.

Being a computer science major it surprises me.

As mentioned in another reply in this thread (which by now seem to have
broken into two pieces), it is meant for a Linear Algebra assignment at
college. I have returned to school again to get a further degree in
Physics, Astronomy and Mathematics.

And the college teacher has given the matrix the name 'P'.
