Another point in favor of multiple dispatching. By the way, tensor expressions should just become ordinary expression with the addition of an index management mechanism, as well as other features such as components data association. Of course some precautions should be taken, for example all indices have to be contracted if you take the exponential of a tensor expression (I am wondering, did anyone ever define a unique and consistent way to generalize the matrix exponential to tensors of any rank?). -- You received this message because you are subscribed to the Google Groups "sympy" group.
