line_min

PURPOSE ^

% [a,fx,nev] = line_min (f, dx, args, narg) - Minimize f along dx

SYNOPSIS ^

function [a,fx,nev] = line_min (f, dx, args, narg)

DESCRIPTION ^

% [a,fx,nev] = line_min (f, dx, args, narg) - Minimize f along dx
%
% INPUT ----------
% f    : string  : Name of minimized function
% dx   : matrix  : Direction along which f is minimized
% args : list    : List of argument of f
% narg : integer : Position of minimized variable in args.  Default=1
%
% OUTPUT ---------
% a    : scalar  : Value for which f(x+a*dx) is a minimum (*)
% fx   : scalar  : Value of f(x+a*dx) at minimum (*)
% nev  : integer : Number of function evaluations
%
% (*) The notation f(x+a*dx) assumes that args == list (x).
