Fast fixed-point matrix format #146

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
This is about 15x faster than mpmath.matrix for both addition and matrix
multiplication (at size 30 x 30). It could be made faster still by using
numpy.array internally.

It might be useful especially as a temporary representation for evaluation
of matrix functions.

I think this is not worth the effort; fp matrices or the Cython types in Sage 
should
be as fast as this anyway.

Yes, and if we really port matrix() to be a frontend to numpy.array, we can get 
this
for free.
