I would suggest reading Charles van Loan's "Introduction to Scientific
Computing". You can get Matlab code to do your operations off his home
page.

LU factorization, with and without pivoting:
http://www.cs.cornell.edu/cv/Books/SCMV/Mfiles/chap6.htm

Cholesky factorization, 6 different versions:
http://www.cs.cornell.edu/cv/Books/SCMV/Mfiles/chap7.htm

QR factorization:
