Fixed on the stable branch. The fix for this regression will be part of a 4.0.1 bug fix release.

Mike: As regressions, it seems to me that this
(and bug #45207) should qualify for inclusion in
the current 4.0. These were both detected in
4.0.0rc's, which is what the rc's are for!.

Since you have patches shouldn't they be applied
to the current stable??

Thanks for your bug report, I can confirm this. The regression is due to the recent fix for bug #44722. The tests only exercise the 3-argument form of linsolve, a test will be added as part of the fix for this bug.

As a workaround, you can add an empty struct as the 3rd argument and it should work:

Hello !

In octave 4.0.0rc3 and 4.0.0rc4 the linsolve function appears to be broken.

Observed behaviour (4.0.0rc3 and 4.0.0rc4):

Expected behaviour (octave 3.8.1 and 4.0.0rc2):

Diff'ing the file "linsolve.m" between 4.0.0rc2 and 4.0.0rc3 I notice several changes which might have introduced this regression. I noticed it first in 4.0.0rc3 and can confirm that this persists in 4.0.0rc4. For the rc3 and rc4 builds the same compiler and configure options(i.e. only --prefix) have been used as for the rc2 build where linsolve is ok.

Running a "make check" on the 4.0.0rc3 source code for which I first noticed the problem returns:

Best Regards

Christof
