  Hello everybody

I have recently quit matlab for octave. I am trying to use fminunc in a matlab-like style and get the following error:

error: unknown option 'maxit'
error: evaluating if command near line 136, column 5
error: evaluating if command near line 135, column 3
error: evaluating while command near line 116, column 1
error: called from `read_options' in file `/usr/share/octave/2.1.57/site/m/octave-forge/miscellaneous/read_options.m'
error: evaluating assignment expression near line 157, column 5
error: called from `minimize' in file `/usr/share/octave/2.1.57/site/m/octave-forge/optim/minimize.m'
error: evaluating if command near line 125, column 1
error: called from `fminunc' in file `/usr/share/octave/2.1.57/site/m/octave-forge/optim/fminunc.m'
error: called from `mycrfchaintrain' in file `mychaintrain.m'
error: evaluating for command near line 71, column 5

My function mychaintrain contains this call to fminunc():

options = optimset('GradObj', 'on', 'Diagnostics', 'off', 'Display','off', 'MaxIter', 20, 'TolFun', 1e-10, 'TolX', 1e-10); [w, finalErr, exitFlag, out] = fminunc(@mychainErrAndGrad, w, options, features, labels, C);

What am I doing wrong?

Many thanks in advance!

Gael
