This example shows a MATLAB M-file for defining a combination signal in a one line compact format and then plotting it.
MATLAB M-File example6.m:% % File Name: example6.m % % Description: This M-file is used to plot the combination signal % % xv = 0.5 t^2 + 2t for 0<=t<=1 % = -0.5 t^2 + 3 for 0<=t<=2 % t = 0.0:0.005:2.0; % define time vector xv = (0.5*t.*t + 2*t).*(t>=0) - (0.5*t.*t + 2*t).*(t>=1) ... + (-0.5*t.*t + 3).*(t>=1); % define signal in one line plot(t,xv); % plot signal grid; xlabel('time (seconds)'); ylabel('x(t)*v(t)'); title('EE341.01: Plot of x(t)*v(t) from Classroom Example');MATLAB Plot Generated:
