This table gives some values of an unknown function $${\displaystyle f(x)}$$.
Interpolation provides a means of estimating the function at intermediate points, such as See more

Other forms of interpolation can be constructed by picking a different class of interpolants. For instance, rational interpolation is interpolation by rational functions See more

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 … See more

If we consider $${\displaystyle x}$$ as a variable in a topological space, and the function $${\displaystyle f(x)}$$ mapping to a Banach space, then the problem is treated as … See more

Gaussian process is a powerful non-linear interpolation tool. Many popular interpolation tools are actually equivalent to particular … See more

Multivariate interpolation is the interpolation of functions of more than one variable. Methods include bilinear interpolation See more

The term extrapolation is used to find data points outside the range of known data points.
In curve fitting problems, the constraint that the interpolant … See more
