<< Hello all,

<< I wonder if there's any builtin command to "normalize" a matrix, e.g

Following does this for matrix m:
"m / sum(m)"

If you want to do it for each row then work on transpose as follows:
Nap "t =3D transpose(m)"
Nap "result =3D transpose(t / sum(t))

<< Eigenvectors also?
No sorry. I would like more linear algebra functions for such things.

<< I figure I'd ask before I create loops etc..
Most things can be done without loops.
