Comment #1 on issue 2415 by matt...@gmail.com: Poly(x, x) * I != I * Poly(x, x)
http://code.google.com/p/sympy/issues/detail?id=2415
This is a well known problem with the core. Poly itself works fine with non-Basic operand, e.g.:
In [1]: 2*Poly(x) Out[1]: Poly(2*x, x, domain='ZZ') In [2]: Poly(x)*2 Out[2]: Poly(2*x, x, domain='ZZ') -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
