Interpolation - Wikipedia
WEBInterpolation provides a means of estimating the function at intermediate points, such as = We describe some methods of interpolation, differing in such properties as: accuracy, cost, number of data points needed, and smoothness of the resulting interpolant function.
Linear interpolation - Wikipedia
WEBGiven the two red points, the blue line is the linear interpolant between the points, and the value y at x may be found by linear interpolation. In mathematics, linear interpolation is a method of curve fitting using linear polynomials to construct new data points within the range of a discrete set of known data points.
Interpolation (Definition, Formula) | Calculation with Examples
WEBMar 13, 2024 · Interpolation. Interpolation is used to forecast or predict values that exist within a data set. It is often considered less risky in comparison with extrapolation. Therefore, investors, traders, and analysts use it in high-stake situations. There are different methods such as linear interpolation, polynomial, and spline interpolation methods.

WEBApr 5, 2024 · interpolation, in mathematics, the determination or estimation of the value of f ( x ), or a function of x, from certain known values of the function. If x0 < … < xn and y0 = f ( x0 ),…, yn = f ( xn) are known, and if x0 < x < xn, then the estimated value of f ( x) is said to be an interpolation.

Interpolation -- from Wolfram MathWorld
WEB5 days ago · The computation of points or values between ones that are known or tabulated using the surrounding points or values. In particular, given a univariate function f=f(x), interpolation is the process of using known values f(x_0),f(x_1),f(x_2),...,f(x_n) to find values for f(x) at points x!=x_i, i=0,1,2,...,n.
WEBInterpolation. Interpolation is the problem of tting a smooth curve through a given set of points, generally as the graph of a function. It is useful at least in data analy-sis (interpolation is a form of regression), industrial design, signal processing (digital-to-analog conversion) and in numerical analysis.
