Hi Sympy community, I've been looking at issue3479<https://code.google.com/p/sympy/issues/detail?id=3479> and trying to fix it by using minlex. Right now I just put the following at the end of def eval(cls, i, j): sort_args = minlex( ( i , j ) ) i = sort_args[0] j = sort_args[1]
However, it still gives me the unchanged result such as: >>>KroneckerDelta(n, m) KroneckerDelta(n, m) >>>KroneckerDelta(m, n) KroneckerDelta(m, n) I guess I still don't fully understand how symbols work in this function. Any help will be appreciated. Regards, Bi Ge -- You received this message because you are subscribed to the Google Groups "sympy" group.
