MoorePenrose PseudoInverse Matrixby Angharad (Pilgrim) 
on Aug 01, 2005 at 18:55 UTC ( #480010=perlquestion: print w/replies, xml )  Need Help?? 
Angharad has asked for the wisdom of the Perl Monks concerning the following question:
I'm trying to write some code to calculate the MoorePenrose Pseudoinverse Matrix of a matrix (strangely enough :) ).
B is the pseudoinverse of A if the following terms are true. I was wondering what the best way to tackle this might be. I'm familisising myself with PDL which is good because it allows me to transpose matrices very easily. I was thinking in terms of something like this The Inverseinv function would then do the tests to see if B does equal A as set up above. As someone relatively inexperienced, I am just asking if this is the best way to go about solving this task and if not, any suggestions as to how else I could tackle it would be much appreciated. I'm not necessarily asking for code by the way, just suggestions, but if you have a snippet or two, that would obviously be appreciated too. Thanks in advance.
