This ststs extension for PHP provides few dozens routines for statistical
computation.
The package is intended for scientists and engineers who need to manipulate
a variety of types of matrices using standard matrix operations. Emphasis is
on the kind of operations needed in statistical calculations such as least
squares, linear equation solve and eigenvalues.
The general purpose of this library is to provide C language procedures related
to cartographic processes. Procedures for each of the processes will be strictly
categorized and although they may share common subfunctions they will not
intersect in scope.
Msieve is a library and utility for factoring large integers using the most
powerful modern algorithms. It features a stable and very fast implementation
of a self-initializing multiple polynomial quadratic sieve (MPQS), plus a
somewhat experimental general number field sieve (GNFS) implementation.
Primary design goals are speed, portability and ease of use. Msieve claims to
be the fastest implementation for factoring general inputs between 40 and 100
decimal digits, but can handle larger input as well.
ocamlgsl is an interface to GSL (GNU scientific library), for the
Objective Caml langage.
Supports base-2, base-10, base-16, and base-256 numbers.
Uses the GMP or BCMath extensions, if available,
and an internal implementation, otherwise.
A package that returns all the combinations and
permutations, without repitition, of a given set
and subset size. Associative arrays are preserved.
This is a port of Phil Karn's Reed-Solomon CODEC library. This package may be
useful to programmers working on data communications software.
This is a port of Phil Karn's SIMD assisted Viterbi CODEC library. This
package may be useful to programmers working on data communications software.
The symeig module contains a Python wrapper for the LAPACK functions to
solve the standard and generalized eigenvalue problems for symmetric
(hermitian) positive definite matrices. Those specialized algorithms give
an important speed-up with respect to the generic LAPACK eigenvalue
problem solver used by NumPy (linalg.eig and linalg.eigh).
