Matrix Magic is an introduction to linear equations and matrix methods used in linear programming, It shows by examples how we use these tools to create models for prediction and simplification of physical problems such as the firing of a projectile in air or solving passive DC and AC circuits or impedance matching in rf circuits. It shows how we can use the chart drawing functions of generic spreadsheet applications to give visual realisations of results. It also serves as an introduction to the application of vector analysis.

The routines, programs and spreadsheets used in Matrix Majic are all available with full workings and code from the link "Accessory" provided above.
