Interpolation In the mathematical field of numerical analysis, interpolation is a type of estimation, a method of constructing (finding) new data points based on the range of a discrete set of known data points. In engineering and science, one often has ...

Craig interpolation In mathematical logic, Craig's interpolation theorem is a result about the relationship between different logical theories. Roughly stated, the theorem says that if a formula φ implies a formula ψ, and the two have at least one atomic variable sy ...

Inbetweening Inbetweening, also known as tweening, is a process in animation that involves creating intermediate frames, called inbetweens, between two keyframes. The intended result is to create the illusion of movement by smoothly transitioning one image in ...

String interpolation In computer programming, string interpolation (or variable interpolation, variable substitution, or variable expansion) is the process of evaluating a string literal containing one or more placeholders, yielding a result in which the placeholders ...

Music

Interpolation (popular music) In popular music, interpolation (also called a replayed sample) refers to using a melody—or portions of a melody (often with modified lyrics)—from a previously recorded song but re-recording the melody instead of sampling it. Interpolation ...

, the inclusion of a re-recorded (rather than sampled) melody from a previous song

Manuscripts

Interpolation (manuscripts) An interpolation, in relation to literature and especially ancient manuscripts, is an entry or passage in a text that was not written by the original author. As there are often several generations of copies between an extant copy of an ancient tex ...
