Part 2: Comments

Any statement in MATLAB that is preceded by a percent sign % is treated as a comment -- that is, it is ignored by the MATLAB compiler.

1. Enter
   
        % Now we will define the coefficients of the polynomial:
        a = 2;
        b = 5;
        c = 6;
2. Enter
   
        n = 3   % n is the number of roots of the equation.

An entire line may be a comment, or just the second part of a line.

In Part 4 of this tutorial, you will learn how you can save the work you do during a MATLAB session into a "diary" file. You should include many MATLAB comments in your work so that later, when you read your diary file, you can see what you were doing.
