plotpv

R2026b

(To be removed) Plot perceptron input/target vectors

plotpv will be removed in a future release. For more information, see Transition Legacy Neural Network Code to dlnetwork Workflows.

For advice on updating your code, see Version History.

Syntax

plotpv(P,T) plotpv(P,T,V)

plotpv(P,T) takes these inputs,

`P`	`R`-by-`Q` matrix of input vectors (`R` must be 3 or less)
`T`	`S`-by-`Q` matrix of binary target vectors (`S` must be 3 or less)

and plots column vectors in P with markers based on T.

plotpv(P,T,V) takes an additional input,

`V`	Graph limits = `[x_min x_max y_min y_max]`

and plots the column vectors with limits set by V.

This example shows how to define and plot the inputs and targets for a perceptron.

p = [0 0 1 1; 0 1 0 1];
t = [0 0 0 1];
plotpv(p,t)

Four input vectors plotted in P(1)-P(2) space, with circles for class 0 and a plus for class 1

Introduced before R2006a

plotpv will be removed in a future release.
