Hi guys, For the benefit of others stuck as I was, or for those working on the ticket, here's a simplified version of what's been working for me over the last few months:
res = mathematica(mathcommand) res_s = repr(res).replace('{','[').replace('}',']').replace ('*^','e').replace('\n','') #Convert string from mathematica syntax to SAGE syntax eval(res_s, {'I': numpy.complex(0,1)}) Note that mathematica uses *^ instead of 10^ or e. There are some other rules in sympy's parser, which is included with sage but is seemingly unused (and possibly has minor whitespace issues?) I had to use Python's eval, rather than sage_eval, because sage_eval seems to die with some long inputs. eval can crash too (with the same EOF error), but it seems to be more robust. Below is an example for which both sage_eval() and eval() die. If anyone could shed light on the matter it would be appreciated. N.B. the string should be a single line, but may get wrapped by your email client. This is Sage Version 3.2.3, Release Date: 2009-01-05 running on Mac OS X 10.5.6, on a Core 2 Duo. Cheers, Felix sage: import numpy sage: sage_eval("[[-1.8932465265296008 + 1.893245401219096*I, 1.6087131626818518e-13 + 0.2695869628135388*I, 4.038436252074007e-13 + 0.5773220560437329*I, 0.040116139014415714 - 1.817230393941216e-12*I, 0.08763251260817738 + 5.075925790798408e-12*I], [-0.31896241585415663 - 0.3189619384222391*I, -0.7736920455160119 + 6.955547249276606e-14*I, -0.09760283144392495 - 1.446620601086579e-13*I, -4.7592693674936015e-12 + 0.11967794129700637*I, 4.505212175542894e-12 - 0.03242615482565919*I], [0.15796096006135588 + 0.1579558759160282*I, 0.1033123763011309 + 5.815070647230414e-13*I, -0.760297341093265 - 1.257605131144146e-12*I, -1.7810239394400185e-11 + 0.16226566764622224*I, 1.135841420918382e-12 - 0.12040909205325775*I], [-0.04396392304349049 + 0.04395777885494245*I, -6.296074772649263e-13 + 0.32696955556039625*I, 4.616307336391401e-12 - 0.25810574383773044*I, -1.2307441793242817 - 1.56307189 [0.03422429098964126 - 0.03425285256357742*I, 3.7616437742471476e-13 + 0.04103981205323293*I, -6.284223141861389e-12 - 0.28800856674905706*I, -0.21213614940591977 + 1.0860881638485864e-10*I, -1.1903766525513024 + 8.411160656862648e-12*I]]", {'I': numpy.complex(0,1)}) ------------------------------------------------------------ File "<string>", line 1 [[-RealNumber('1.8932465265296008') <SNIP> SyntaxError: unexpected EOF while parsing --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
