Question statement

MATLAB: Basic plotting

The basic command to produce plots is plot. Find documentation for it using the documentation search box in the top right corner of MATLAB window. Use the documentation to complete the following tasks.

Note, that in MATLAB every new plot command overwrites previous plots. If you want to keep old plots, use figure command to create a new plot window. If you want to plot a new line in the existing graph use hold on command. Look up these commands in the documentation for more details.

Task:

Give any introductory information the student needs.
