Before we start

The following punctuations and special characters are worth noting:
    The  >>  is the default command prompt in Matlab

    All text after   sign is taken as comment - MATLAB simply ignores anything to the right of this sign.  So your .exe file is not increased.  Therefore use comments liberally

    A succession of three   ...   at the end of the line indicates statement will continue on the next line
        You cannnot split a variable name across two lines
        You cannot continue a comment on the next line

    A semicolon at the end of the line will prevent MATLAB from echoing the information you type on the screen.  Unlike other languages this is not a statement terminator.

    A comma will cause the information to be printed on the screen

    Multiple commands  can be placed on the line seperated by commas or semicolons

    Typing who  at the prompt will display all variables in the workspace

    Typing clear will remove all variables - CAUTION - You cannot recover the information.  Use care in using ClearAlternately you can clear selected variables.  Check help clear

    You can stop Matlab execution at any time by pressing Ctrl-C at any time
