[Numpy-discussion] matrix default to column vector?
Thu Jun 4 11:08:02 CDT 2009
I really don't see any advantage of matrices over arrays for teaching. I
prefer to teach linear algebra with arrays.
I would also like matrices to disappear from numpy. But then one would need
a new implementation of scipy.sparse, which is (very unfortunately)
matrix-based at the moment.
