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])

`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])
