Cubic spline interpolation in c++
WebAs you probably know, the equation of a cubic Bezier curve is C ( t) = ( 1 − t) 3 P 0 + 3 t ( 1 − t) 2 P 1 + 3 t 2 ( 1 − t) P 2 + t 3 P 3 In this equation it doesn't matter whether the control points P 0, P 1, P 2, P 3 are 2D or 3D.

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 ... Webs = spline (x,y,xq) returns a vector of interpolated values s corresponding to the query points in xq. The values of s are determined by cubic spline interpolation of x and y. example. pp = spline (x,y) returns a piecewise …
