Inversion on a non square matrix using PDL (or similar?)by Angharad (Pilgrim) |

Angharad has asked for the wisdom of the Perl Monks concerning the following question:
I'm having a little play with PDL at the moment. Neat but I was wondering if anyone knew of a way in which you can invert a matrix that isnt square.
There is a function in MatLab called pinv which will invert a rectangular matrix. Perhaps there is something similar offered in PDL? Or, if not, does anyone know of another way to implement this using Perl?
