Hi octave-experts,
I'm trying to get P.C. Hansens Regularization Toolbox
(http://www.imm.dtu.dk/~pch/Regutools/index.html) running under Octave.
Basically I'm walking my way through the scripts, waiting until an
error message appears because of missing functions and look for octave
substitutes.
One of these functions is optimset.m. I downloaded Etienne Grossmann's
version from:
http://cvs.sourceforge.net/viewcvs.py/octave/octave-forge/main/optim/
optimset.m?rev=HEAD
On line 44 this function calls setfield.m, which I downloaded, too:
http://users.powernet.co.uk/kienzle/octave/matcompat/scripts/struct/
setfield.m
The call from optimset is:
opt = setfield ();
Octave returns:
error: va_arg: error getting arg number 2 -- only 0 provided
error: evaluating assignment expression near line 36, column 7
error: evaluating while command near line 35, column 1
Is it possible that the call is wrong and that setfield expects some
input, or is there a general difference in how optimset is used under
Matlab and octave?
