To square the elements of an array, use .^2 instead of ^2. To multiply two arrays, use .* insteade of *. For example,
x = 0:0.01:1; % x goes from 0 to 1 by steps of 0.01 y = x.^2; % Each element of y is the corresponding element of x squared z = x .* y; % Each element of z is the corresponding element of x times y. % For example, z(3) will be x(3)*y(3)
The easier way to do this is to plot one curve, give the command "hold on", then plot the second curve.
plot(x,y) hold on plot(x,z)You should plot the first curve in blue and the second curve in red. (To plot in red, give the command
