Ports 搜索

This port installs the prerequisites for Mathworks (r) Matlab for Linux and an installer script (matlab-installer), which automates the somewhat tricky process of installing Linux Matlab. Installing Matlab requires Matlab installation media and a license file and installation key from Mathworks, Inc.

GiNaC is an iterated and recursive acronym for GiNaC is Not a CAS, where CAS stands for Computer Algebra System. It is designed to allow the creation of integrated systems that embed symbolic manipulations together with more established areas of computer science (like computation-intense numeric applications, graphical interfaces, etc.) under one roof.

GRPN is a RPN calculator for the X Window system built using the GIMP Toolkit (GTK). GRPN works with real numbers, complex numbers, matrices, and complex matrices. Numbers can be displayed in 4 different radix modes, and complex numbers can be displayed in either Cartesian or polar form.

Estimation and inference methods for models of conditional quantiles: Linear and nonlinear parametric and non-parametric (total variation penalized) models for conditional quantiles of a univariate response and several methods for handling censored survival data. Portfolio selection methods based on expected shortfall risk are also included.

This is the standalone math library from R -- a language and environment for statistical computing and graphics. See ports/math/R. To use the routines in your own C or C++ programs, include #define MATHLIB_STANDALONE #include <Rmath.h> and link against -lRmath.

This is a collection of stopgap replacements for standard math functions missing from libm in various supported versions of FreeBSD. The functions are slower than the existing libm functions, but are more accurate than many naive replacements. Exceptions are largely ignored. N. Beebe's extended C version of the ELEFUNT package is used to provide regression tests for some of the real-valued functions.

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.

Mathomatic is a highly portable, general purpose CAS (Computer Algebra System). Mathomatic can: * Solve, simplify, and compare algebraic equations, * Perform calculus transformations, * Help with finite series analysis, * Perform complex number and polynomial arithmetic, * Generate efficient C or Java code from equations.

METIS is a set of serial programs for partitioning graphs, partitioning finite element meshes, and producing fill-reducing orderings for sparse matrices. The algorithms implemented in METIS are based on the multilevel recursive-bisection, multilevel k-way, and multi-constraint partitioning schemes developed in our lab. METIS provides high-quality partitions, is extremely fast, and produces low-fill orderings.
