This is an application which shows and offers the possibility to compare different interpolation methods.
Interpolation is an important topic in Numerical Analysis designated to compute a function which passes through a set of points. Using this application you are able to introduce points by a simple tap on the graph.

Basic features:

-Make screenshots of the graph and save them in the Photo album;
-Edit the set of points by deleting or adding a certain point which can be introduced from keyboard;

-Implemented methods:

1. Linear interpolation
2. Lagrange interpolation
3. Newton's divided difference polynomial for interpolation
4. Piecewise quadratic interpolation
5. Piecewise cubic interpolation
6. Natural spline interpolation

-Zoom in and out on the graph using pinch gesture;
-Move around the graph by panning;
-Double-tap with two fingers to return to origin of coordinates.
