Follow-up Comment #33, bug #46330 (project octave):
For the examples
[Inf 1; 1 1] \ [4; 3] % Matlab [0; 3]
[nan 1; 1 1] \ [4; 3] % Matlab [nan; nan]
I'm still seeing this:
octave:1> [Inf 1; 1 1] \ [4;3]
warning: matrix singular to machine precision
warning: matrix singular to machine precision
** On entry to DLASCL parameter number 4 had an illegal value
error: exception encountered in Fortran subroutine dgelsd_
octave:1> [nan 1; 1 1] \ [4;3]
warning: matrix singular to machine precision, rcond = nan
** On entry to DLASCL parameter number 4 had an illegal value
error: exception encountered in Fortran subroutine dgelsd_
In comment #29 Mike said that the patch should avoid calls to XERBLA, but that
doesn't seem to be the case.
I'm using HG ID 8971508e21c8.
