Purpose

Plot error surface of single-input neuron

Syntax

• plotes(WV,BV,ES,V)
  

Description

plotes(WV,BV,ES,V) takes these arguments,

WV	1 x N row vector of values of W
BV	1 x M row vector of values of B
ES	M x N matrix of error vectors
V	View (default = [-37.5, 30])

and plots the error surface with a contour underneath.

Calculate the error surface ES with errsurf.

Examples

• p = [3 2];
  t = [0.4 0.8];
  wv = -4:0.4:4; bv = wv;
  ES = errsurf(p,t,wv,bv,'logsig');
  plotes(wv,bv,ES,[60 30])
