MathUtilInterp Method (DateTime, DateTime, Double, ExtrapolationTypes)

1-D linear interpolation (table lookup) Interpolates to find y, the value of the underlying function yTable at the point x. xTable must be a monoton increasing array of the same length as yTable. For x values outside xTable extrapolation is applied. Extrapolation method is specified.
