O-Matrix Tutorial

The following tutorial provides a walk through of core O-Matrix concepts for many typical data analysis, modelling, and visualization tasks. Working through this sequence typically takes a couple hours and will provide a fairly deep understanding of O-Matrix to enable you to solve a broad range of problems.

The examples in omwin\example, and the Example Navigator provides more in-depth illustrations of a broad range of O-Matrix capabilities as applied in typical analysis applications.

Executing Examples
Each of the sections in the table below contains examples. The easiest way to execute examples in these sections is to use the Windows Copy and Paste functions. As an example, hold down the left mouse button and highlight the following blue text:
     for i = 1 to 5 begin
          print i
Then select the Edit | Copy menu item in you web browser. Then switch to the O-Matrix application, place the cursor in the command line , and select the Edit | Paste menu item in O-Matrix. O-Matrix will reply
in the Command window.
