[sympy] sparsematrix upgrade

2012-09-25 Thread smichr
I've spent the last several days trying to incorporate Sherjilozair's smallchanges PR into matrices. matrices is still rough in design, namely there are lots of methods in MatrixBase that should probably be in MutableMatrix since SparseMatrix derives from MatrixBase and Sparse's .mat is a dicti

I only looked at this very quickly: I get >>> from sympy import * >>> pg00 = Symbol('pg00') >>> pg01 = Symbol('pg01') >>> eq1 = sympify(pg01**2/pg00**2) >>> eq2 = sympify(1.0 - 2*pg01/pg00) >>> eq3 = sympify(pg01*(1.0 - pg01/pg00)) >>> eq = [eq1,eq2,eq3] >>> print eq [pg01**2/pg00**2, 1.0 - 2*pg

Sure. The main work will be reviewing pull requests. This is something that you can actually help out with outside of GCI as well. We may also need some help in the application writing stage, and with creating tasks for the students (I'll post more info on those here as they come up). Aaron Meu
