The Macaulay2 language and design has a number of improvements over that of Macaulay, allowing for infinite coefficient rings, new data types, and other useful features. Using the experience with Macaulay, Grayson and Stillman began work on Macaulay2 in 1993. The Macaulay system showed that it was possible to solve actual problems in algebraic geometry using Gröbner basis techniques, but by the early 1990s, limitations in its architecture were becoming an obstruction. They named Macaulay after Francis Sowerby Macaulay, an English mathematician who made significant contributions to algebraic geometry. Stillman, along with Dave Bayer had authored the predecessor system, Macaulay, beginning in 1983. Both the system and the programming language are published under the GNU General Public License version 2 or 3. The interpreter itself is written in a custom type safety layer over C. The algebraic algorithms that form the core functionality are written in C++ for speed. This language is intended to be easy to use for mathematicians, and many parts of the system are indeed written in the Macaulay2 language. Macaulay2 uses its own interpreted high-level programming language both from the command line and in saved programs. It can also use emacs or GNU TeXmacs as a user interface.
Macaulay2 has an interactive command-line interface used from the terminal (see § Sample session). The Journal of Software for Algebra and Geometry has published numerous packages and programs for Macaulay2. Nearly 200 packages are included in the distribution of Macaulay2 as of 2019, and notable package authors include Craig Huneke and Frank-Olaf Schreyer. In addition, the system has been extended by a large number of packages. This core functionality includes arithmetic on rings, modules, and matrices, as well as algorithms for Gröbner bases, free resolutions, Hilbert series, determinants and Pfaffians, factoring, and similar. Secondly, get X server running with emacs GUI 1.Macaulay2 is built around fast implementations of algorithms useful for computation in commutative algebra and algebraic geometry. Tip: use the command in bash "lsb_release -a" to retrieve your Ubuntu's version.
Hit Start then type "bash", or open command prompt and type "bash". Get 'bash' for Windows and M2: 1.) Get Ubuntu "bash" in cmd Install "Linux subsystem for Windows" with ubuntu.įollow instructions: 2.) Open Ubuntu bash.
See the following sections for the steps for installation of, firstly, the Linux subsystem then M2, followed by installing and setting up an X server with emacs coupled with M2. However, Windows 10 for developers and insider builds come with a new feature, "Linux subsystem for Windows". For most Windows distro-s, use Cygwin to get Linux bash and through that, M2 command to start Macaulay2. Macaulay 2, M2 for short, currently is mainly developed for Linux distros.
