plotep (Neural Network Toolbox)

Plot a weight-bias position on an error surface

h = plotep(w,b,e)
h = plotep(w,b,e,h)

Description

plotep is used to show network learning on a plot already created by plotes.

plotep(W,B,E) takes these arguments,

W - Current weight value.

B - Current bias value.

E - Current error.

and returns a vector H, containing information for continuing the plot.

plotep(W,B,E,H) continues plotting using the vector H returned by the last call to plotep.

H contains handles to dots plotted on the error surface, so they can be deleted next time, as well as points on the error contour, so they can be connected.
