[Numpy-discussion] still no cross product for new array type

Just browsing through the new array PEP to see if there's support for 3-vector operations, such as cross product, norm, length functions. Sadly I don't see any. It's something I think is lacking from Numeric and numarray and would like to see implemented. Is it a deliberate choice not to include any? I understand that vectors are sufficiently different animals that you could argue that they shouldn't be supported. I use them enough to think that they should be. Gary Ruben
