plotfit

(To be removed) Plot function fit

plotfit 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

plotfit(net,inputs,targets)

plotfit(net,inputs1,targets1,name1,inputs2,targets2,name2,...)

plotfit(...,'outputIndex',outputIndex)

Description

plotfit(net,inputs,targets) plots the output function of a network across the range of the inputs inputs and also plots target targets and output data points associated with values in inputs. Error bars show the difference between outputs and targets.

The plot appears only for networks with one input.

Only the first output/targets appear if the network has more than one output.

plotfit(net,inputs1,targets1,name1,inputs2,targets2,name2,...) plots multiple sets of data.

plotfit(...,'outputIndex',outputIndex) plots using an optional parameter that overrides the default index of the output element.

Examples

Plot Output and Target Values

This example shows how to use a feedforward network to solve a simple fitting problem.

[x,t] = simplefit_dataset;
net = feedforwardnet(10);
net = train(net,x,t);
plotfit(net,x,t)

Input Arguments

net — Input network

network object

Input network, specified as a network object. To create a network object, use for example, feedforwardnet or narxnet.

inputs — Network inputs

matrix | cell array

Network inputs, specified as a matrix or cell array.

targets — Network targets

matrix | cell array

Network targets, specified as a matrix or cell array.

Version History

Introduced in R2008a
