Hi,

I recently started using Strata for linear interpolation and extrapolation.Prior to this I had developed a custom method to calculate extrapolated points

y[0] + (y[1] - y[0]) * (Xn - x[0]) / (x[1] - x[0]) for points on short end

y[y.length - 2] + (y[y.length - 1] - y[y.length - 2]) * (Xn - x[x.length - 2])

/ (x[x.length - 1] - x[x.length - 2]) for long end.

However strata extraplators have used a epsilon component that changes the value of extrapolated point.

What is the purpose of EPS?
