Details:
In current tip on the default branch (721a4a83cba6, 2012-02-14), fminunc.m
does not work if the option "FunValCheck" is set to "on".
octave:1> fminunc (@ (x) x^2, 1, optimset ("FunValCheck", "on"))
error: `jx' undefined near line 353 column 33
error: evaluating argument list element number 1
error: called from:
error: /home/olaf/devel/src/octave/scripts/optimization/fminunc.m at line
353, column 3
error: /home/olaf/devel/src/octave/scripts/optimization/fminunc.m at line
149, column 6
This is due to a typo (probably after copy-and-paste from fsolve), jx is the
gradient returned by the user function and should be named gx here. After
correcting this:
octave:1> fminunc (@ (x) x^2, 1, optimset ("FunValCheck", "on"))
error: `complexeqn' undefined near line 355 column 11
error: called from:
error: /home/olaf/devel/src/octave/scripts/optimization/fminunc.m at line
353, column 3
error: /home/olaf/devel/src/octave/scripts/optimization/fminunc.m at line
149, column 6
This is again probably due to a copy-and-paste mistake, the option
"ComplexEqn" is not applicable to fminunc (it expects a real scalar returned
by the user function) and these two lines with the test should be deleted.
A small patch will be attached in the next comment, I want to get the bug
number first.
