Chebfun – Numerical Computing with Functions
- tempodox 11y agoSeems to require a MATLAB installation. I would have loved a stand-alone version.
- dagw 11y agoThere are a couple of projects inspired by chebfun that are adding similar functions to other languages: * https://github.com/ApproxFun/ApproxFun.jl https://github.com/ApproxFun/ApproxFun.jl (Julia) * https://github.com/olivierverdier/pychebfun https://github.com/olivierverdier/pychebfun (Python) * http://nines.cs.kuleuven.be/software/CHEBINT/ http://nines.cs.kuleuven.be/software/CHEBINT/ (Octave)

- mturmon 11y agoThis is a cool package that offers a new capability. I've been trying to find a use for it -- although Mathematica could do some of this also. They have a nice examples page (http://www.chebfun.org/examples/ http://www.chebfun.org/examples/). Here's one on convolving probability distributions that is much easier and cleaner than discretising the problem manually (http://www.chebfun.org/examples/stats/ProbabilityConvolution.html http://www.chebfun.org/examples/stats/ProbabilityConvolution...). Of course, also much more accurate. The same could be said of computations of expectations or probabilities on such distributions.
