Comment #24 on issue 2011 by nicolas....@gmail.com: less self-confident simplify
http://code.google.com/p/sympy/issues/detail?id=2011
This is the code in Matrix.is_symmetric(): def symmetric(self): if not self.is_square: return False m = self.clone() m.simplify() return (m == m.transpose()) I think using something like (m - m.transpose()).simplify() == self.zeros(self.rows, self.cols) would be better instead. I'll look at this tomorrow... -- You received this message because you are subscribed to the Google Groups "sympy-patches" group. To post to this group, send email to sympy-patches@googlegroups.com.
