Matrix Multiplication

An interactive demo (with voiceover explanation) on Matrix Multiplication, A = LU, and PA = LU

Eigenvalue Demonstrations

The demonstrations below employ Java® applets with voice-over narration to show some Eigenvalue concepts.

Demo 1 - This 3-minute demo shows eigenvectors of 2 by 2 matrices

The demo is also broken into 7 independent pieces:

Demo 2 - Powers AnV lead toward the top eigenvalue/eigenvector

Mini-lectures on Eigenvalues

The mini-lectures with voice-over narration below help to explain some key Eigenvalue concepts.
