plotregression(targets,outputs) plots the linear regression of targets relative to outputs.

plotregression(targs1,outs1,'name1',targs2,outs2,'name2',...)generates multiple plots.

This example shows how to plot the linear regression of a feedforward net.

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

Figure Neural Network Training (19-Aug-2023 11:57:11) contains an object of type uigridlayout.

y = net(x);

Figure Regression (plotregression) contains an axes object. The axes object with title Regression: R=0.99999, xlabel Target, ylabel Output ~= 1*Target + -0.00095 contains 3 objects of type line. One or more of the lines displays its values using only markers These objects represent Y = T, Fit, Data.

Input Arguments
