This is the way to do this. A piecewise cubic Hermite interpolant has the nice property that it is simply assured to be both continuous and differentiable across the break points, because the value and first derivative at each end of an interval is given. This is, IMHO, a very pretty way to build up a piecewise cubic. – greek restaurants in seattle wa
