[sage-devel] Manipulating diff. eqs. in Mathematica using pattern matching

2008-08-24 Thread Jason Merrill
In hopes that it may be a useful reference during the current work on symbolics, I wrote a toy Mathematica program for transforming a single higher order ODE into a system of first order ODEs. Most of the free numerical differential equation solvers I've seen want input in the form y'[x] == f(y,x
