optimplotx

Plot the value of the parameters of an optimization algorithm

SYNOPSIS

optimplotx ( x , optimValues , state )

Description

This function creates and updates a plot of the value of the parameters 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 optimplotx 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" , optimplotx );
[x fval] = fminsearch ( rosenbrock , [-1.2 1] , opt );
