Hi! Sympy - Today I wanted to do some matrix algebra homework but ran into trouble as it seems that matrix multiplication with different dimension matrixes/vectors does not work:
P = Matrix([1, 0, 2]) # Vector P=(1, 0, 2) M = Matrix([ 1/2, 0, 1/2], [0, sqrt(3)/2, 0], [1/2, 0, sqrt(3)/2]) T = M*M # Base transformation Pnew = P*T.inv() ShapeError: :( I have also tried to set P as a tuple or a list but these are giving me a "TypeError: can't multiply sequence by non-int of type 'Add'' Am I doing something wrong or is this stuff yet unimplemented? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
