optimplotfval
Plot the function value of an optimization algorithm
SYNOPSIS
optimplotfval ( x , optimValues , state )
Description
This function creates and updates a plot of the function value, depending on the number of iterations. It is a pre-defined plot function which should be used as an option of the "PlotFcns" option.
Example
In the following example, we use the optimplotfval
function
for use with the fminsearch
function.
function y=rosenbrock(x) y = 100*(x(2)-x(1)^2)^2 + (1-x(1))^2; endfunction opt = optimset ( "PlotFcns" , optimplotfval ); [x fval] = fminsearch ( rosenbrock , [-1.2 1] , opt );
