Wow, that was quick. Here is the output of it: A = (16*x**2*y**2*(1 - x)**2*(1 - y)**2)e_z B = curl(A) = (-16*x**2*y**2*(1 - x)**2*(2 - 2*y) + 32*y*x**2*(1 - x)**2*(1 - y)**2)e_x+(16*x**2*y**2*(1 - y)**2*(2 - 2*x) - 32*x*y**2*(1 - x)**2*(1 - y)**2)e_y div(B) = 0 This geometric algebra approach is cool. > I also have some improvements to __str__() for the multivector class and > documentation upgrades I will be submitting soon.

Do you think some people would miss the grad_ext() and grad_int() methods? If so, maybe you can create aliases for curl and div. I'll study GA more, I definitely understand your passion for it. :) Ondrej --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
