hello, sorry for this newbie question, but I need an answer quite quickly.
I see PDL when I was looking for a tool that make SVD decomposition in Perl (I first want to use bindings to GSL but I don't know how to make perl->C bindings...) I need SVD decomposition to make pca data compression. My question is quite simple: can I use PDL outside of te perldl shell?? I try this: use PDL; use PDL::Matrix; print trace(([[1,2,3],[4,5,6]])); But it give me that: [EMAIL PROTECTED]:~/progr/perl$ ./PDL.sample.pl Undefined subroutine &main::trace called at ./PDL.sample.pl line 12. And I don't know if PDL is the thing I'm looking for or if there is another package that can be useful for me... thanks, Laurent.
