<p><b>New page</b></p><div>'''Interpolation''' is a method of constructing new data points within the range of a discrete set of known data points. It is widely used in many fields including mathematics, physics, and computer graphics.<br />
<br />
== Overview ==<br />
<br />
In the mathematical field, interpolation is a type of estimation, a method of constructing new data points within the range of a discrete set of known data points. The primary function of interpolation in mathematics is to estimate values that fall between two known values.<br />
<br />
In computer graphics, interpolation is used to produce a smooth gradient or to resize digital images. In the realm of physics, it is used to predict values for an element based on the known values of surrounding elements.<br />
<br />
== Types of Interpolation ==<br />
<br />
There are several types of interpolation methods, including:<br />
<br />
* '''[[Linear Interpolation]]''' - This is the simplest method of interpolation. In this method, two points are connected by a straight line and the value of an intermediate point is estimated using this line.<br />
<br />
* '''[[Polynomial Interpolation]]''' - This is a more general form of interpolation which involves fitting a polynomial that passes through given points.<br />
<br />
* '''[[Spline Interpolation]]''' - This method involves fitting a special type of piecewise polynomial called a spline to the data points.<br />
<br />
* '''[[Rational Interpolation]]''' - This is a type of interpolation where the interpolant is a rational function.<br />
<br />
== Applications ==<br />
<br />
Interpolation has a wide range of applications in various fields. Some of the notable applications include:<br />
<br />
* '''[[Image Processing]]''' - Interpolation is used in image processing to increase the size of an image or to correct distortions.<br />
<br />
* '''[[Computer Graphics]]''' - In computer graphics, interpolation is used to create smooth transitions between points and lines.<br />
<br />
* '''[[Numerical Analysis]]''' - Interpolation is used in numerical analysis to solve differential equations and to approximate functions.<br />
<br />
* '''[[Geostatistics]]''' - In geostatistics, interpolation is used to predict unknown values for any geographic location, based on the values at surrounding locations.<br />
