The Matrix Template Library (MTL) is a high-performance generic component library that provides comprehensive linear algebra functionality for a wide variety of matrix formats. As with the Standard Template Library (STL), MTL uses a five-fold approach, consisting of generic functions, containers, iterators, adaptors, and function objects, all developed specifically for high performance numerical linear algebra. Within this framework, MTL provides generic algorithms corresponding to the mathematical operations that define linear algebra. Similarly, the containers, adaptors, and iterators are used to represent and to manipulate concrete linear algebra objects such as matrices and vectors.

MUMPS is a Distributed Multifrontal Solver (F90, MPI based) with Dynamic Distributed Scheduling to accomodate both numerical fill-in and multi-user environment. - Solution of large linear systems with symmetric positive definite matrices; general symmetric matrices; general unsymmetric matrices. - Version for complex arithmetic. - Parallel factorization and solve phases (uniprocessor version also available). - Iterative refinement and backward error analysis. - Various matrix input formats: assembled format; distributed assembled format; elemental format. - Partial factorization and Schur complement matrix. - Several orderings interfaced : AMD, AMF, PORD, METIS

NTL is an object oriented library for number theory, written by Victor Shoup. It provides objects and methods for - arbitrary length integers - finite fields - polynomials over fields - extensions of fields. - vectors and matrices over extensions - finite rings Unless you define WITHOUT_GMP, NTL requires libgmp4.

Numdiff is a little program that can be used to compare putatively similar files line by line and field by field, ignoring small numeric differences or/and different numeric formats. Equivalently, Numdiff is a program with the capability to appropriately compare files containing numerical fields (and not only). % numdiff file1 file2

This is a component of SPARK 2015: Those looking for the automatic theorem prover known as Alt-Ergo should refer to math/alt-ergo instead

The FFLAS-FFPACK library provides dense linear algebra routines over word-size prime finite fields.

Abakus is a simple calculator for KDE, based on a concept of Roberto Alsina's. Think of it as bc (the command-line calculator) with a nice GUI.

This port contains ten types of distributions supplementing those built into R: Inverse Gauss, Kruskal-Wallis, Kendall's Tau, Friedman's chi squared, Spearman's rho, maximum F ratio, the Pearson product moment correlation coefficient, Johnson distributions, normal scores and generalized hypergeometric distributions. In addition, two random number generators of George Marsaglia are included. The port is supplemented by an R benchmark based upon the work of Grosjean, Steinhaus, et al.

Orpie is a fullscreen RPN calculator for the console. Its operation is similar to that of modern HP calculators, but data entry has been optimized for efficiency on a PC keyboard. Features include extensive scientific calculator functionality, command completion, and a visible interactive stack. Orpie is the successor of math/rpc by the same author; it has been completely rewritten in Ocaml, and offers a number of features that were not available in the older program.

RPy is a very simple, yet robust, Python interface to the R Programming Language. It can manage all kinds of R objects and can execute arbitrary R functions (including the graphic functions). All the errors from the R language are converted to Python exceptions. Any module that later were installed on the R system, can easily be used from within Python, without introducing any changes.
