Interpolation space — In the field of mathematical analysis, an interpolation space is a space which lies in between two other spaces. The main applications are in Sobolev spaces, where spaces of functions that have a noninteger number of derivatives are interpolated… … Wikipedia
Trilinear interpolation — is a method of multivariate interpolation on a 3 dimensional regular grid. It approximates the value of an intermediate point (x, y, z) within the local axial rectangular prism linearly, using data on the lattice points. For an arbitrary,… … Wikipedia

Polynomial interpolation — In the mathematical subfield of numerical analysis, polynomial interpolation is the interpolation of a given data set by a polynomial. In other words, given some data points (such as obtained by sampling), the aim is to find a polynomial which… … Wikipedia
Lebesgue constant (interpolation) — For other uses, see: Lebesgue constant. In mathematics, the Lebesgue constants (depending on a set of nodes and of its size) give an idea of how good the interpolant of a function (at the given nodes) is in comparison with the best polynomial… … Wikipedia
