Subject: pchip coefficients: what do they mean? From: Jim Rockford Date: 4 Apr, 2013 05:54:45 Message: 1 of 6 
I would like to be able to use the output coefficients from pchip to do various things, such as estimate the derivative at a point. This is easy enough to do with spline, since one knows that the coefficients correspond to a generic cubic polynomial in each subinterval. You can differentiate the cubic analytically and proceed, and it's clear what the coefficients mean.
