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 );
