hi Eddie,
thank you!
very useful for me.
However I think that the "left" pseudo inverse should me
Code:
 IF n==c THEN RETURN (TRN(mtx)*mtx)^-1*TRN(mtx);

also you could use
Code:
 r:=rowDim(mtx); c:=colDim(mtx); n:=RANK(mtx);

without calculate at all d:=SIZE(mtx) and so on...
Obviously you should set also
Local r,c,n;

I hope you could appreciate my little two cents

Salvo
