Spline Interpolation

Input:

x
xi, yi, i=1,...,N

Calculation:

y"j, j=1,...,N-1
Computed from the first derivative continuity across the interval points.

Output:

y = Ayj + Byj+1 + Cy"j + Dy"j+1

Where

A = (xj+1 - x) / (xj+1 - xj)
B = (x - xj) / (xj+1 - xj)
C = 1/6(A3 - A)(xj+1 - xj)2
D = 1/6(B3 - B)(xj+1 - xj)2
