Cholesky/Pascal identity

Hi, you wrote "an upper triangular matrix is not a symmetric matrix => the Cholesky decomposition or Cholesky factorization is a decomposition of a Hermitian, positive-definite matrix"

And yet I get: cholesky(pascal_upp(i)) == identity(i)

Combinations code for Maxima

Hi Arbautjc, aka Capra H!

Kudos 4 your Maxima code for combinations, it works fine, on maxima, even on moodle (-stack plugin), unless the rest of my code. If I get it 2 work once, I'd probably need a GPL licence like the other moodle stuff. Can you give it an additional licence like GPLv3+ and possibly say so on your Userpage?

I wrote automated math questions btw, like 1/3-1/4=?, it chooses denominators from a combinations-list of (2,3)(2,4)(2,6)(3,..).
