My Favorite MATLAB Demos

In 1988, while I was with Ardent Computer in Silicon Valley, I gave a talk that previewed MATLAB graphics. The title was "Pictures of Matrices". At the time, a mathematician friend of mine asked.

  Why would anyone want pictures of matrices?

My response is the graphics demonstrations that we have done over the years. Here is a baker's dozen of my favorite examples.

Vibes

The vibrating L-shaped membrane.

Eigshow

One of my all-time favorite MATLAB examples is eigshow.

Eden

This sketch of the MathWorks Logo was made by Eden Rajapakse when she was ten years old. Her blog post has received more "likes" than any other post.
