Linear Program Polynomial Interpolation Method
Interpolation via Gaussian processes [ ] is a powerful non-linear interpolation tool. Many popular interpolation tools are actually equivalent to particular Gaussian processes. Gaussian processes can be used not only for fitting an interpolant that passes exactly through the given data points but also for regression, i.e., for fitting a curve through noisy data. In the geostatistics community Gaussian process regression is also known as. Other forms of interpolation [ ] Other forms of interpolation can be constructed by picking a different class of interpolants. For instance, rational interpolation is interpolation by using, and is interpolation by using. Another possibility is to use.
The can be used if the number of data points is infinite. Sometimes, we know not only the value of the function that we want to interpolate, at some points, but also its derivative. This leads to problems. When each data point is itself a function, it can be useful to see the interpolation problem as a partial problem between each data point.

Bicubic Interpolation in digital signal processing [ ] In the domain of digital signal processing, the term interpolation refers to the process of converting a sampled digital signal (such as a sampled audio signal) to that of a higher sampling rate () using various digital filtering techniques (e.g., convolution with a frequency-limited impulse signal). In this application there is a specific requirement that the harmonic content of the original signal be preserved without creating aliased harmonic content of the original signal above the original Nyquist limit of the signal (i.e. Torrent Kelly Payne. , above fs/2 of the original signal sample rate). An early and fairly elementary discussion on this subject can be found in Rabiner and Crochiere's book Multirate Digital Signal Processing.
