Introduction to MATLAB®

MATLAB^® is an abbreviation for MATrix LABoratory. It is a very powerful mathematical tool used to perform numerical computation using matrices and vectors to obtain two- and three-dimensional graphs. MATLAB can also be used to perform complex mathematical analysis.

Getting Started

1. Open MATLAB by clicking Start Programs MATLAB R2006a MATLAB R2006a.

2. Open a new M-file by clicking File New M-File.

3. Type the code in the M-File.

4. Save the file as fn.m (e.g., Lab1.m).

5. Simulate the code by doing one of the following:

(a) Click on Debug Run.

(b) Press F5

(c) On the tool bar, click the icon Run.

Use HELP by pressing F1.

Use % at the beginning of a line for comments.
