Anyone care to comment on scipy's useability for solving ODEs versus,
say, Mathematica or Matlab? I'm not very familiar w/ either of the 'M'
packages, but may have them forced on me soon unless I'm able to say,
no, we are better off w/ scipy for user metric 1, 2, ... If scipy comes
up short in some way, sign me up as able and willing to help. Apologies
for hijacking your thread, your example is perfect.
