Exempel på hur man kan använda INTERPOLATION i en mening

• 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.
• To calculate the IQR, the data set is divided into quartiles, or four rank-ordered even parts via linear interpolation.
• Because polynomials are among the simplest functions, and because computers can directly evaluate polynomials, this theorem has both practical and theoretical relevance, especially in polynomial interpolation.
• Improvements include enhancements in encoding, digital filtering, scan interpolation, interlaced line scanning, and ghost cancellation.
• In numerical analysis and approximation theory, basis functions are also called blending functions, because of their use in interpolation: In this application, a mixture of the basis functions provides an interpolating function (with the "blend" depending on the evaluation of the basis functions at the data points).
• Geostatistics is intimately related to interpolation methods, but extends far beyond simple interpolation problems.
• Interpolation search resembles the method by which people search a telephone directory for a name (the key value by which the book's entries are ordered): in each step the algorithm calculates where in the remaining search space the sought item might be, based on the key values at the bounds of the search space and the value of the sought key, usually via a linear interpolation.
• The Whittaker–Shannon interpolation formula or sinc interpolation is a method to construct a continuous-time bandlimited function from a sequence of real numbers.
• This is intuitively correct as well: the "curvier" the function is, the worse the approximations made with simple linear interpolation become.
• In 3D computer graphics, it is sometimes referred to as "Phong shading", particularly if the model is used with the interpolation method of the same name and in the context of pixel shaders or other places where a lighting calculation can be referred to as “shading”.
• The resulting interpolation polynomial minimizes the problem of Runge's phenomenon and provides an approximation that is close to the best polynomial approximation to a continuous function under the maximum norm, also called the "minimax" criterion.
• Of the songs on this album, an interpolation of the first part of the song "Smile Happy" was used in the song "It Wasn't Me" by Shaggy featuring RikRok.
• The Whittaker–Shannon interpolation formula is mathematically equivalent to an ideal low-pass filter whose input is a sequence of Dirac delta functions that are modulated (multiplied) by the sample values.
• The method has demonstrated that it has a better interpolation performance than Piecewise polynomials (splines) to mitigate the Runge phenomenon.
• In numerical analysis, polynomial interpolation is the interpolation of a given bivariate data set by the polynomial of lowest possible degree that passes through the points of the dataset.
• For equispaced nodes, Lagrange interpolation is susceptible to Runge's phenomenon of large oscillation.
• If the value of a function is known at several points, cubic interpolation consists in approximating the function by a continuously differentiable function, which is piecewise cubic.
• SciPy contains modules for optimization, linear algebra, integration, interpolation, special functions, FFT, signal and image processing, ODE solvers and other tasks common in science and engineering.
• Bilinear interpolation, an extension of linear interpolation for interpolating functions of two variables on a rectilinear 2D grid.
• Again, values for the edge fluxes can be reconstructed by interpolation or extrapolation of the cell averages.
