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)

`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])
