Sturla My recollection, from discussions, at the time of the introduction of the @ operator, was that there was no intention to disturb the existing Matrix class. I see the matrix as a long recognized mathematical entity. On the other hand, the array is a very useful computational construct, used in a number of computer languages. Since matrices are now part of some high school curricula, I urge that they be treated appropriately in Numpy. Further, I suggest that consideration be given to establishing V and VT sub-classes, to cover vectors and transposed vectors.
