newRPL: Simplified matrices proposal

[Paul Dale]

This approach is likely to run into difficulties when you start implementing the matrix functions. What algorithms will you use to invert a matrix? There are lots of them for numeric matrices with a variety of different characteristics (speed, stability, easy reuse). For symbolic, far less so.

Then consider things like Eigen solutions and singular value decompositions? Nice numeric solutions, pretty horrible symbolically.

You are going to have to distinguish numeric matrices somewhere along the line, if not the various special form numerics (row, tri-diagonal, triangular, blocked).


Still, delaying these decisions so the user is oblivious to them might be beneficial.
