[Numpy-discussion] matrix norm

I'm curious why scipy/numpy defaults to calculating the Frobenius norm
for matrices [1], when Matlab, Octave, and Mathematica all default to
calculating the induced 2-norm [2]. Is it solely because the Frobenius
norm is easier to calculate, or is there some other good mathematical
reason for doing things differently?
Thanks,
Jason
