Package org.hipparchus.util

Convenience routines and common data structures used throughout the Hipparchus library.

Interface Summary

Interface	Description
Incrementor.MaxCountExceededCallback	Defines a method to be called at counter exhaustion.
IterationListener	The listener interface for receiving events occurring in an iterative algorithm.
MathArrays.Function	Real-valued function that operates on an array or a part of it.

Class Summary

Class	Description
ArithmeticUtils	Some useful, arithmetics related, additions to the built-in functions in Math.
BigReal	Arbitrary precision decimal number.
BigRealField	Representation of real numbers with arbitrary precision field.
Combinations	Utility to create combinations (n, k) of k elements in a set of n elements.
CombinatoricsUtils	Combinatorial utilities.
CombinatoricsUtils.FactorialLog	Class for computing the natural logarithm of the factorial of n.
CompositeFormat	Base class for formatters of composite objects (complex numbers, vectors ...).
ContinuedFraction	Provides a generic means to evaluate continued fractions.
Decimal64	This class wraps a double value in an object.
Decimal64Field	The field of double precision floating-point numbers.
FastMath	Faster, more accurate, portable alternative to Math and StrictMath for large scale computation.
FieldSinCos<T>	Holder for both sin and cosine values.
FieldTuple<T extends RealFieldElement<T>>	This class allows to perform the same computation of all components of a Tuple at once.
Incrementor	Utility that increments a counter until a maximum is reached, at which point, the instance will by default throw a MathIllegalStateException.
IterationEvent	The root class from which all events occurring while running an IterationManager should be derived.
IterationManager	This abstract class provides a general framework for managing iterative algorithms.
KthSelector	A Simple Kth selector implementation to pick up the Kth ordered element from a work array containing the input numbers.
MathArrays	Arrays utilities.
MathUtils	Miscellaneous utility functions.
MultidimensionalCounter	Converter between unidimensional storage structure and multidimensional conceptual structure.
OpenIntToDoubleHashMap	Open addressed map from int to double.
OpenIntToFieldHashMap<T extends FieldElement<T>>	Open addressed map from int to FieldElement.
Pair<K,V>	Generic pair.
Precision	Utilities for comparing numbers.
ResizableDoubleArray	A variable length primitive double array implementation that automatically handles expanding and contracting its internal storage array as elements are added and removed.
SinCos	Holder for both sin and cosine values.
Tuple	This class allows to perform the same computation of all components of a Tuple at once.

Enum Summary

Enum	Description
MathArrays.OrderDirection	Specification of ordering direction.
MathArrays.Position	Specification for indicating that some operation applies before or after a given index.
PivotingStrategy	A strategy to pick a pivoting index of an array for doing partitioning.
ResizableDoubleArray.ExpansionMode	Specification of expansion algorithm.
