interpolaatsiooni
Interpolaatsiooni (interpolation) is a method in numerical analysis and statistics for estimating unknown values within the range defined by a set of known data points. It aims to construct a function that agrees with the measured values at their positions and enables predictions at intermediate positions. The technique is used when data are sampled discretely and continuous values are needed between samples.
Common approaches include linear interpolation, which connects neighboring data points with straight segments; polynomial interpolation, which
Interpolation is distinct from extrapolation, which estimates values outside the known range. It can introduce errors
Applications span numerical simulation, computer graphics, digital signal processing, weather and geospatial data, and data-driven modeling.
