Comment #8 on issue 1487 by ryanlists: fcode: print sympy expressions as Fortran code http://code.google.com/p/sympy/issues/detail?id=1487 I think two printers with as much core in common as possible makes a lot of sense. I see myself using this code in the future and I see Fortran code

Comment #12 on issue 1477 by goodrich.ben: Printing with double subscripts http://code.google.com/p/sympy/issues/detail?id=1477 Looks good to me, although someone who understands Python really well should review it. Printing in these odd cases is certainly better than it used to be in 0.6.4,

I was looking at the status of my issues today and saw that 1493 was listed as accepted. Unless someone has figured out how to make it pass the tests in test_solvers.py, I think my patch breaks tests. I changed the status back to NeedsReview. Sorry if I did this in error. If you figured out

Just to be clear, the patch for issue 1495 doesn't fix issue 1493, it makes it so 1493 fails on my computer so that I might try and debug it. On Sun, Jun 28, 2009 at 8:30 AM, Ryan Krauss ryanli...@gmail.com wrote: I was looking at the status of my issues today and saw that 1493 was listed as

Alan, I brought this issue up a while back and submitted a patch that fixed the same issue in solve. I haven't gotten around to writing the same piece of code for diff, but this is on my to do list for the same reasons as yours. I think the fundamental issue is that Symbols are treated as
