Follow-up Comment #29, bug #48807 (group octave):=0A=0AAttached is CSET tha=
t implements Matlab-compatible gsvd in Octave=0A(file bug48807_gsvd_2026062=
3_110.cset)=0A=0AAlternatively there are 3 files that can be replaced in yo=
u octave sources if=0ACSET would not work for some reasons (old version?)=
=0A(file gsvd_files.tgz)=0A=0AThe code uses somewhat different algorithm th=
an Natlab (according to MW=0Awebpage), so I am curious how bad we are doing=
 WRT matlab's implementation. So=0Ahere are some benchmarks=0A(also posted =
at=0Ahttps://octave.discourse.group/t/help-with-matlab-gsvd-benchmarks/7606=
?u=3Ddasergatskov=0A)=0A(file gsvd_bench.tgz); if anyone could run those on=
 their matlab and post=0Aresults here or in Discourse, that would be great.=
