Plotting and Links

Here is a more advanced example and a link to another tutorial on plotting.

Multiple Plots

For the more adventursome, here is an example file that plots multiple curves in colors:

% everything following a % sign is ignored by Matlab.
%
t = 0:0.0001:.05;  % create a vector from 0 to .05 in .0001  increments
omegad = 200*2*pi
y1 = cos(omegad*t);
y2 = sin(omegad*t);
plot(t,y1,'r-',t,y2,'g--') % plot command with red solid line and green dashed line.
title('sine and cosine')   %labels and titles.
xlabel('time (s)')         %these must appear after the
ylabel('x(t)')             %plot command.
print sines -dps  %creates a file called sines.ps that you can print from  UNIX.

The print command is not needed on PC/MAC unless you want to save the file
for posterity.
