Angharad has asked for the wisdom of the Perl Monks concerning the following question:
Hi Monks!
Further to a post I made a day or so ago regarding the pseudoinverse of a mxn matrix, I proceeded to create the following script .. attempting to implement the equation pseudoinvB = (B^tB)^-1B^t where B^t = transpose of non square matrix B. Does this look OK to people or not?
