Plotting arrays of data are easy in MATLAB.
Recall one can define 30 points between 0 and 2 by saying
**xlist=linspace(0, 2*pi, 30)**.
To plot the sine function between 0 and 2
one says

**ylist=sin(xlist)**

then

**plot(xlist, ylist)**.

To plot more functions, keep giving x, y pairs such as

**plot(xlist, ylist, xlist, 2*ylist)**.

Note that we explicitly give MATLAB the x and y values for the plot.

At this point a new window appears on your screen containing the plot.
This window will remain open during your session with MATLAB.
The MATLAB **clf** command clears the graphics (figure) window.
