This 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.
