What should be the plot command?

deltaSignal = abs(testSignal - referenceSignal);

percentageDifference = deltaSignal ./ referenceSignal; % Percent by element.

meanPctDiff = mean(percentageDifference); % Average percentage over all elements

If you can please tell me how does the plot command looks like for the code above.

What exactly do you want to plot and how?

Answer 1

[Walter Roberson]

plot([deltaSignal(:), percentageDifference(:)])

However, it is likely that the two are on fairly different scales, so you probably want something more like

Fs = 44100;        %sampling frequency. Example value.

t = (0 : length(deltaSignal) - 1) ./ Fs;
plotyy(t, deltaSignal, 'b', t, 100 * percentageDifference, 'gp');

Read the documentation about plot

doc plot

Look at this example

t=0:0.01:10
y1=sin(t)
y2=cos(t)
plot(t,y1,t,y2)
