I should add that there is a "shar" file of functions from S Poetry, so you need not type them in yourself.

I think perhaps you are looking for something like "symsqrt" which is given on page 285 of S Poetry.

Hi,
How can one decompose the matrix M into
M= W * t(W)
I know of the chol() command but I am looking more for hypersphere decomposition and spectral decomposition.
Thanks.
