This function uses vectorised methods to determine the locations of maxima and minima where they exist within a piecewise spline fit. The matlab built-in functions for determining the maxima and minima, by differentiating the pp spline and finding its zeros (using the Spline toolbox), are quite...

PP = PCHIPD(X,Y,D) provides the piecewise cubic polynomial which interpolates values Y and derivatives D at the sites X. This is meant to augment the built-in Matlab function PCHIP, which does not allow the user to specify derivatives.X must be a vector.If Y and D are vectors, then Y(i) and D(i)...
