It seems to me that the error comes from feeding a function which uses i into fast_float (called by the plotting functions to compile the function to be plotted into an optimized form). I tried a simpler function using i and got the same error:
sage: plot3d(x + y + i, (x, 0, 1), (y, 0, 1)) Traceback (click to the left for traceback) ... TypeError: float() argument must be a string or a number sage: from sage.ext.fast_eval import fast_float sage: fast_float(x + i, 'x') Traceback (click to the left for traceback) ... TypeError: float() argument must be a string or a number It would make sense for the low-level representation used by fast_float not to include a concept of imaginary numbers. Have you had success plotting any other functions that use imaginary numbers? There should be a mechanism to fall back to using the unmodified function in the event that fast_float fails to convert the function. --~--~---------~--~----~------------~-------~--~----~ 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 -~----------~----~----~----~------~----~------~--~---
