Gaussian Elimination Animation

I made an animation of the Gaussian Elimination step in my QS program.

The matrix is 605x606, White = 0, Black = 1

That's a pretty darn cool animation.

jasonp, and chance of an animation of Block Lanczos?

It would be very boring. Random garbage -> random garbage -> answer

In block Lanczos, the matrix is not modified. You start with a random dense vector (or actually 64 of them). Each iteration modifies the vector, but it continues to appear random until the end when the answer pops out.
