In this paper, we propose a modified Lagrange type interpolation operator to approximate functions in Sobolev spaces by continuous piecewise polynomials. In order to define interpolators for "rough" ...

Interpolation is taking the difference at different points to create a line or curve on a graph. For business owners, this is ideally the growth curve.

MathCAD provides a number of interpolation and curve-fitting functions, so that, given a set of X-Y data points, you can estimate the Y value for any given X coordinate. Unfortunately, these functions ...
