## Uses of Interface
cern.colt.function.DoubleFunction

Packages that use DoubleFunction
cern.colt.map | Automatically growing and shrinking maps holding objects or primitive data types such as `int`, `double`, etc.
cern.colt.matrix | Matrix interfaces and factories; efficient and flexible dense and sparse 1, 2, 3 and d-dimensional matrices holding objects or primitive data types such as `int`, `double`, etc; Templated, fixed sized (not dynamically resizable); Also known as multi-dimensional arrays or Data Cubes.
cern.colt.matrix.impl | Matrix implementations; You normally need not look at this package, because all concrete classes implement the abstract interfaces of `cern.colt.matrix`, without subsetting or supersetting.
cern.colt.matrix.linalg | Linear Algebraic matrix computations operating on `DoubleMatrix2D` and `DoubleMatrix1D`.
cern.jet.math | Tools for basic and advanced mathematics: Arithmetics and Algebra, Polynomials and Chebyshev series, Bessel and Airy functions, Function Objects for generic function evaluation, etc.
cern.jet.random | Large variety of probability distributions featuring high performance generation of random numbers, CDF's and PDF's.
cern.jet.random.engine | Engines generating strong uniformly distributed pseudo-random numbers; Needed by all JET probability distributions since they rely on uniform random numbers to generate random numbers from their own distribution.
hep.aida.bin | Multisets (bags) with efficient statistics operations defined upon; This package requires the Colt distribution.
