A Graphical Tool for Linear Algebra
The procedure eshow graphically illustrates some concepts from introductory
linear algebra. When passed a 2x2 matrix A as an argument, the procedure computes
the product Au for each of several unit vectors u, and displays the results as
an animation. Additionally, each frame contains textual annotations including
decimal approximations of u, |u|, Au, and |Au|.
To use eshow, follow these steps...
- Cut the Maple commands from the Maple for eshow
page and paste it into a Maple worksheet. Press enter.
- Enter a matrix. For example, use the command
A:= matrix([[2,0],[1,1]]); Press enter.
- Enter the command eshow(A); Press enter, and watch your animation.
