errsurf

Error surface of single input neuron

Syntax

• errsurf(P,T,WV,BV,F)
  

Description

errsurf(P,T,WV,BV,F) takes these arguments,

• P - 1 x Q matrix of input vectors.

  T - 1 x Q matrix of target vectors.

  WV - Row vector of values of W.

  BV - Row vector of values of B.

  F - Transfer function (string).

and returns a matrix of error values over WV and BV.

Examples

• p = [-6.0 -6.1 -4.1 -4.0 +4.0 +4.1 +6.0 +6.1];
  t = [+0.0 +0.0 +.97 +.99 +.01 +.03 +1.0 +1.0];
  wv = -1:.1:1; bv = -2.5:.25:2.5;
  es = errsurf(p,t,wv,bv,'logsig');
  plotes(wv,bv,ES,[60 30])
