WebCubic Hermite Interpolation. The cubic Hermite interpolant takes non-equispaced data and interpolates between them via cubic Hermite polynomials whose slopes must be provided. This is a very nice interpolant for solution skeletons of ODEs steppers, since numerically solving y ' = f ( x , y) produces a list of positions, values, and their ...
