Major New Release at Chebfun – Two Dimensional Capabilities

Perhaps you've read about Chebfun before here or on Cleve''s blog. Chebfun allows you to do numerical computing with functions and not simply numbers. If not, you might want to investigate. If so, you may be very interested in new capabilities available.


Major New Capability

Just recently, the Chebfun team released a major new capability on their site. While Chebfun is extremely useful, it was restricted to solving problems in one dimension. Now you may solve problems with two independent variables using Chebfun2! As before, their website includes code you can freely download and many interesting examples. The examples are well documented and easy to learn from. I will soon have time to explore Chebfun2 because of an irrational amount of airline time. I also love how easy it is to install - you can do it from MATLAB. They kindly post the code right on the website so you can paste it into your running session.

Many Examples

They have many examples included in the software, and posted on their web site, using the publish command in MATLAB. The high-level examples are organized into these categories:
  1. Approximation
  2. Complex Analysis
  3. Geometry
  4. Optimization
  5. Statistics
  6. Rootfinding
  7. Vector Calculus
  8. Fun !
I hope with this breadth of examples, you are able to find ones interesting or relevant (or both) to you. Once you've gotten a chance to try out Chebfun2, I'd love to hear about your experiences. Post them here to share with us.
