hello,
I'm a little confuse with PDL::Matrix...
Is the code in "Work in Progress"? I see in the PDL manpages (on the web
site) that not all the operators are redefined...
Here is my problem: I have to use SVD to compress a quite huge matrix (~5000
columns), so I'm using SVD on R, but I want to implement this in my perl
interface. What I want is to pass my matrix and get back another matrix (not
a piddle) but:
I do not understand how the matrix is saved: by columns (I suppose) or by
lines, still mdims seems to not work... ("" print $datasAdjust->mdims() ""
don't write anything on the terminal...)
I don't know how to scale the matrix (centering is sufficiant, no need to
realy scale)
I don't know how to make an inner product (The manpages say that they is not
yet...)
I don't know how to manipulate the matrix by hand or to get the informations
back to my own format (not a piddle)
So, is this package usable, or I have to find another way (perhaps use the
GSL library whith binding from perl...?)
If it is usable, where can I get some tutorial or documentation other than
the manpages that give me the tricks I need?
regards,
Laurent.
