Syntax
optimset('PlotFcns', @optimplotx)Selects the plot for use with solvers such as fminsearch.
Description
Passed in the PlotFcns option, it draws a bar for each component of the current point, so the position of the search can be followed as it moves. It is meant to be called by the solver, not directly.
Example
Follow the point
opts = optimset('PlotFcns', @optimplotx);
x = fminsearch(@(x) (x(1) - 1)^2 + x(2)^2, [0 0], opts);In the app, the bars are drawn below the code.
