I'm using the language from Corless's book [A Graduate Introduction to Numerical Analysis: From a viewpoint of backward error](https://www.amazon.com/Graduate-Introduction-Numerical-Methods-Viewpoint-ebook/dp/B00H5IOGR8/); also it's Definition 1.4 of your link, no? If the usage...

The interpolant is the solution, in Corless's language.

@HDembinski : Hugely useful discussion, thanks! I dropped the interquartile range into boost.math a couple days ago, so perhaps a two-pass recommendation for future users might be: ``` using boost::math::statistics::interquartile_range;...

@HDembinski : There are tons of splines in Boost.Math. Presumably one of any of the functions in `boost/math/interpolators` would do?
