i'm taking this amazing course andrew ng on coursera machine learning , want implement of things larn in "native language" create sure i'm understanding course of study material. found this matrix class written shankar manamalkav (2011) , few adjustment managed pretty much matrix functions needed, except one: equivalent pinv() octave. although i'm not sure pinv() (analytically), stands pseudo-inverse of matrix.

i'm not sure if help (i dont know octave), @ this:

lapack::pseudoinverse — calculate inverse of matrix

good luck
