as I understand from Octave sources, svd is a wrapper to fortan
functions in the Lapack lib. Would it be possible to add a gsvd
(Generalised Singular Value Decomposition) function, as gsvd routines
are readily available in Lapack 3 ?


Pascal Dupuis

I think you're asking the wrong people? May the question should be do you want to implement it :-)

It should be relatively easy to do so, if the oct-file links directly to the GSVD. However, the better way to do it would be to add the functionality to the Fsvd function itself and fix the SVD and ComplexSVD class to allow calls to gsvd as well.
