*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?
