Cubic hermite polynomial interpolation
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 ... WebFeb 28, 2011 · This is done by defining n-1 cubic Hermite polynomials, with the i-th polynomial defined using the data at nodes x(i) and x(i+1). The resulting function …

WebFeb 7, 2015 · You compute a cubic polynomial for each segment (i.e. for each range between two given data points) by considering the data points defining the segment and the two adjacent data points, just as in your example. If you define the cubic polynomial as P ( x) = a 0 + a 1 x + a 2 x 2 + a 3 x 3 Webinterpolation. Two types of piecewise polynomial interpolation techniques will be discussed. 7.1 Hermite Interpolation For each data point (xi, fi), if the derivative of the unknown function f at xi, f ′(xi), is also given, and the piecewise interpolant is required to interpolate the derivatives as well, then the resulting piecewise ...
