[Octave-bug-tracker] [bug #60273] Wrong result in GSVD

[Rik]

Update of bug #60273 (project octave):

                  Status:                    None => Confirmed

Follow-up Comment #1:

Confirmed.

The problem is only with matrix X as stated.  The code in question is in
liboctave/numeric/gsvd.cc.  The code there calls LAPACK to perform the actual
gsvd calculation.

There are several possibilities.  1) Octave is not calling LAPACK correctly,
2) there is a bug in LAPACK, 3) or matrix X is meant to be calculated outside
of LAPACK via some other method such as the suggested


X = A'*U*inv(C)
