As it contains two parameters - C0, C1, the interpolation function should be developed with two interpolation points. Assumed that the values of the function y=f(x) in the x1 and x2 interpolation points were respectively y1 and y2, the fellow formula would be deduced from the formula (3): . The formula (7) can be inferred by introducing the formula (5) into (6): And by comparing the coefficients of C0 and C1 in formula (7) and (4), the fellowing formula can be developed: [ Last edited by masterpine on 2008-10-15 at 16:14 ] |
