plotep

Plot a weight-bias position on an error surface

Syntax

• 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.
