SageMath is designed partially as a free alternative to the general-purpose mathematics products Maple and MATLAB. It can be downloaded or used through a web site. SageMath comprises a variety of other free packages, with a common interface and language. SageMath is developed in Python.
The Bug Finder module identifies software bugs by performing static program analysis on source code. It finds defects such as numerical computation, programming, memory, and other errors. It also produces software metrics such as Comment density of a source file, Cyclomatic complexity, Number of lines, parameters, call levels, etc. in a ...
RFinder ("repeater finder") is a subscription-based website and mobile app. RFinder's main service is the World Wide Repeater Directory ( WWRD ), which is a directory of amateur radio repeaters . RFinder is the official repeater directory of several amateur radio associations.
FreeMat is a free open-source numerical computing environment and programming language, [1] similar to MATLAB and GNU Octave. [2] In addition to supporting many MATLAB functions and some IDL functionality, it features a codeless interface to external C, C++, and Fortran code, further parallel distributed algorithm development (via MPI), and has plotting and 3D visualization capabilities.

MATLAB (an abbreviation of "MATrix LABoratory" [22]) is a proprietary multi-paradigm programming language and numeric computing environment developed by MathWorks.MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages.
It was a free tool for academics. Jack Little, who would eventually set up the company, came across the tool while he was a graduate student in electrical engineering at Stanford University. [3] [4] Little and Steve Bangert rewrote the code for MATLAB in C while they were colleagues at an engineering firm.
Given: a function f : A R from some set A to the real numbers Search for: an element x 0 in A such that f ( x 0 ) ≤ f ( x ) for all x in A . In continuous optimization, A is some subset of the Euclidean space R n , often specified by a set of constraints , equalities or inequalities that the members of A have to satisfy.
There are a few reviews of free statistical software. There were two reviews in journals (but not peer reviewed), one by Zhu and Kuljaca [26] and another article by Grant that included mainly a brief review of R. [27] Zhu and Kuljaca outlined some useful characteristics of software, such as ease of use, having a number of statistical procedures and ability to develop new procedures.
