I am using matlab to plot several figures and hope these figure use the same plot options. To be more specific, it looks something like this.
N = 20; Fs = 20
Solution with unique plotting function:
subplot(312); myplot(t,y)
Save myplot function as a separate m-file.
myplot
function myplot(t,x) plot(t, x, 'bs-', 'MarkerFaceColor', 'b', 'LineWidth', 3); end
