INTERP2D(R1, R2, N)

Description
INTERP2D returns interpolated values for a 2-dimensional vector. R1 and R2 have to be same size.

Parameters
R1
A range reference points to x values of the vector

R2
A range reference points to y values of the vector

N
A numerical value or range on which the interpolation value will be based.

Example
0   A   B
1   1   2.5
2   3   4.5
3   5   8.2
4   7   10.5
5   9   13.4
INTERP2D(A1..A5, B1..B5, C1..C2) =
