Cubic hermite

WebCubic Hermite interpolation requires different data (function value and derivative at two end points) than quadratic polynomial fit (three function values). Also, cubic Hermite interpolation fits a cubic to 4 dof, hence is order O ( h 4), while a quadratic polynomial fits 3 dof only, hence is order O ( h 3). If a cubic polynomial were fitted by ...
