fminunc

PURPOSE ^

% [x,v,flag,out,df,d2f] = fminunc (f,x,opt,...) - M*tlab-like optimization

SYNOPSIS ^

function [x,fval,flag,out,df,d2f] = fminunc (fun,x0,opt,varargin)

DESCRIPTION ^

% [x,v,flag,out,df,d2f] = fminunc (f,x,opt,...) - M*tlab-like optimization
%
% Imitation of m*tlab's fminunc. The optional 'opt' argument is a struct,
% e.g. produced by 'optimset'.
%
% Supported options
% -----------------
% Diagnostics, [off|on] : Be verbose
% Display    , [off|iter|notify|final]
%                       : Be verbose unless value is 'off'
% GradObj    , [off|on] : Function's 2nd return value is derivatives
% Hessian    , [off|on] : Function's 2nd and 3rd return value are
%                         derivatives and Hessian.
% TolFun     , scalar   : Termination criterion (see 'ftol' in minimize)
% TolX       , scalar   : Termination criterion (see 'utol' in minimize)
% MaxFunEvals, int      : Max. number of function evaluations
% MaxIter    , int      : Max. number of algorithm iterations
%
% These non-m*tlab are provided to facilitate porting code to octave:
% -----------------------
% 'MinEquiv' , [off|on] : Don't minimize 'fun', but instead return the
%                         option passed to minimize.
%
% 'Backend'  , [off|on] : Don't minimize 'fun', but instead return
%                         [backend, opt], the name of the backend
%                         optimization function that is used and the
%                         optional arguments that will be passed to it. See
%                         the 'backend' option of minimize.
%
% This function is a front-end to minimize.
