PCOMP - factor loadings [message #29503]

I'm using IDL 5.4 to do a principal components analysis
using PCOMP. This all seems to work fine, however, I
also need the factor (component) loadings. This is probably
buried in the calculations or relatively easily extractable from
the covariance matrix. Would someone tell me how to get from
PCOMP to the factor loadings? There doesn't seem to be an IDL
routine for doing this, although some appropriate matrix operations
are probably all that's required.

I'd appreciate the help.

Thanks,

John Piccirillo
