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):
octave:1> a=[1,2;3,4;]; b=[1;2];
octave:2> linsolve(a,b)
error: 'trans_A' undefined near line 103 column 7
error: called from
linsolve at line 103 column 3
Expected behaviour (octave 3.8.1 and 4.0.0rc2):
octave:1> a=[1,2;3,4;]; b=[1;2];
octave:2> linsolve(a,b)
ans =
0.00000
0.50000
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:
PASS 12612
FAIL 0
XFAIL 15
SKIPPED 302
Best Regards
Christof
