Dear Ed, I think you was "too fast and easy" in your comment. Tensors are entities that have special rules when changing the coordinate system. That's not the case for "any matrix".
Best regards, Sacha ________________________________________ De : CCP4 bulletin board [ccp...@jiscmail.ac.uk] de la part de Ed Pozharski [epozh...@umaryland.edu] Tensor is just a fancy name for a multidimensional array + definition of the rule by which different tensors may be multiplied.
