How to plot RMSE vs Epochs graph

I understand that using the plotperform function gives the MSE vs Epochs graph. However, I need to plot RMSE vs Epochs graph. Are there any way to do this?

As I understand it, ‘RMSE’ is the square-root of the MSE value.

I am not certain what you want to do. Here are two options (using the example from the plotperform documentation):

[x,t] = bodyfat_dataset;
net = feedforwardnet(10);
[net,tr] = train(net,x,t);
plotperform(tr)

yt = get(gca, 'YTick');
set(gca, 'YTick', yt, 'YTickLabel',compose('%.1f',sqrt(yt)))    % Convert ‘YTickLabel’ Values To RMSE

Ls = findobj(gca, 'Type','line');                               % Calculate RMSE For All ‘Line’ Object Y-Values
for k1 = 1:numel(Ls)
    yval{k1} = Ls(k1).YData;
    rmse{k1} = sqrt(yval{k1});
end

The entire code converts the Y-tick values and calculates the RMSE.

Experiment to get the result you want.
