This is a cool package that offers a new capability.  I&#x27;ve been trying to find a use for it -- although Mathematica could do some of this also.<p>They have a nice examples page (<a href="http:&#x2F;&#x2F;www.chebfun.org&#x2F;examples&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.chebfun.org&#x2F;examples&#x2F;</a>).  Here&#x27;s one on convolving probability distributions that is much easier and cleaner than discretising the problem manually (<a href="http:&#x2F;&#x2F;www.chebfun.org&#x2F;examples&#x2F;stats&#x2F;ProbabilityConvolution.html" rel="nofollow">http:&#x2F;&#x2F;www.chebfun.org&#x2F;examples&#x2F;stats&#x2F;ProbabilityConvolution...</a>).  Of course, also much more accurate.  The same could be said of computations of expectations or probabilities on such distributions.
