Hey all, There is a debate on whether or not that when defining vectors, should there be a TypeError when adding vectors in different coordinate systems. For example:
In [1]: C1 = CoordSysCartesian('C1') In [2]: C2 = CoordSysCartesian('C2') (+1) In [3]: vector = C1.x * C1.i + C2.y * C2.j (-1) In [3]: vector = C1.x * C1.i + C2.y * C2.j TypeError: The vector should be well-defined. Please vote with +1 or -1 below. The current representation is +1. Thanks, Justin -- You received this message because you are subscribed to the Google Groups "sympy" group.
