I wanted to go deep into at least one of the articles to further

responding. The one I have chosen is the one named "Computing the Matrix

Cosine" by N.J. Higham and M.I. Smith.

After compiling octave, I have written a draft of a would be cosm

function. It seems to compare well to the actual funm in octave and

real(expm()).

This has brought up to a couple of questions about testing matrix

funcions: is there any way to systematically test a (matrix) function?

The second one is about Padé approximations in octave, right now I am

using sympy (sympy.org) for that purpose.

Either way, my plan for the gsoc is to follow the articles and try to

effectively implement and test all of them.

Finally, I provide you with the m file and new (working) links to the

articles.
