The purpose of the Eigenvector Viewer is to allow you to see
linear transformations in 2 dimensions by entering a matrix
and clicking on the screen to input a vector x, and see
a resultant vector b = A x.
By finding the input vectors that overlap with the output
vectors, one can find the real eigenvectors and eigenvalues of the matrix.
Fundamentals
Enter your matrix in the space provided, and modify the graph scale as
needed.
Features
The "sweep" button will let you put the applet on auto-pilot,
sweeping out a full 360 degrees to search for eigenvectors and
eigenvalues.
