Spline Interpolation Example in Python - DataTechNotes

WebIn linear interpolation, the estimated point is assumed to lie on the line joining the nearest points to the left and right. Assume, without loss of generality, that the x -data points are in ascending order; that is, x i < x i + 1, and let x be a point such that x i < x < x i + 1. Then the linear interpolation at x is: $ y ^ ( x) = y i + ( y i ... WebThis forms part of the old polynomial API. Since version 1.4, the new polynomial API defined in numpy.polynomial is preferred.
