## Package org.apache.sis.math Description

A set of mathematical objects and algebraic utilities. This package provides:

- Mathematical functions as static methods in `MathFunctions` and `DecimalFunctions`.
- `Statistics` accumulator, optionally with statistics on derivatives and tabular formatting.
- Simple equations for `Line` and `Plane` with capability to determine the coefficients from a set of coordinates.
  Note: `Line` and `Plane` classes are not geometric objects since they are not bounded in space. For example the `Line2D` geometry have starting and ending points, while the `Line` class in this package extends to infinite.
- `Vector` of real numbers, typically as views over arrays of primitive types. Those views make abstraction of the data type (e.g. `float`, `double`, `int`, unsigned `int`, etc.).
