but a nc factoring routine is available
If factor_nc is not accepted then it's unlikely that factor will be fixed. But with factor_nc factor could be made to just pass off anything that is non-commutative to facctor_nc:
factor_nc(A*B-B*A)
A*B - B*A (The branch didn't try to solve the collect issue.) -- You received this message because you are subscribed to the Google Groups "sympy-patches" group.
