# 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|.
