Linear interpolation.

Pascal
procedure Linear1D(X: TVec; Y: TVec; PiecePoly: TPiecePoly); overload;

Description

The Linear1D procedure interpolates lines between consecutive (X,Y) pairs. Linear1D does not return interpolated points. It constructs piece-wise polynomial, which can be used to evaluate ( by using the PiecePoly.Evaluate method) the linear functions. To directly obtain interpolated values, use the Interpolate routine.

Notes

X values must be monotonic or the result will not be valid.
