PGPLOT
PGPLOT is a device-independent graphics subroutine library written starting in 1983 by Tim Pearson, a professor at the California Institute of Technology. PGPLOT is written mostly in FORTRAN with a modular output API that allows output to several dozen types of plotting device. PGPLOT has been widely used in the academic and scientific communities, because it provides both low-level (glyph, point, line, and area) plotting primitives and also high-level facilities for drawing graphs. PGPLOT may be redistributed to third parties and modified, but only in binary form. Neither the original nor modified source code are allowed to be redistributed. The most recent version of PGPLOT is 5.2.2, released in February 2001, although third parties have written unofficial patches that include support for additional devices, 64 bit systems, and RGB (true color) plotting. PGPLOT provides C and Fortran 77 interface. There are also several user-contributed bindings, such as C++, perl, python, rub ...

Matplotlib
Matplotlib is a plotting library for the Python programming language and its numerical mathematics extension NumPy. It provides an object-oriented API for embedding plots into applications using general-purpose GUI toolkits like Tkinter, wxPython, Qt, or GTK. There is also a procedural "pylab" interface based on a state machine (like OpenGL), designed to closely resemble that of MATLAB, though its use is discouraged. SciPy makes use of Matplotlib. Matplotlib was originally written by John D. Hunter. Since then it has had an active development community and is distributed under a BSD-style license. Michael Droettboom was nominated as matplotlib's lead developer shortly before John Hunter's death in August 2012 and was further joined by Thomas Caswell. Matplotlib is a NumFOCUS fiscally sponsored project. Matplotlib 2.0.x supports Python versions 2.7 through 3.10. Python 3 support started with Matplotlib 1.2. Matplotlib 1.4 is the last version to support Python 2.6. Matplo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Python (programming Language)
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000 and introduced new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 3.0, released in 2008, was a major revision that is not completely backward-compatible with earlier versions. Python 2 was discontinued with version 2.7.18 in 2020. Python consistently ranks as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grace (plotting Tool)
Grace is a free WYSIWYG 2D graph plotting tool, for Unix-like operating systems. The package name stands for "GRaphing, Advanced Computation and Exploration of data." Grace uses the X Window System and Motif for its GUI. It has been ported to VMS, OS/2, and Windows 9*/NT/2000/XP (on Cygwin). In 1996, Linux Journal described Xmgr (an early name for Grace) as one of the two most prominent graphing packages for Linux. History Grace is a descendant of the ACE/gr plotting tool (also known as Xvgr), based on Xview libraries from OpenWindows. Xvgr was originally written by Paul Turner of Portland, Oregon, who continued development until version 4.00. In 1996, development was taken over by the ACE/gr development team, led by Evgeny Stambulchik at the Weizmann Institute of Science, Israel. Development of Xmgr was frozen at version 4.1.2 in 1998 and the Grace project was started as a fork, released under the GPL. The name stands for "GRaphing, Advanced Computation and Exploration ...

Pyxplot
Pyxplot is a free software command-line graph-plotting and vector graphics package. Its interface is similar to that of gnuplot, but its graphics engine is optimised to produce output in a style appropriate for inclusion in academic journals. The LaTeX typesetting system is used to render all text labels, making it easy to annotate graphs with mathematical expressions. In addition, Pyxplot has many more flow control constructs than gnuplot, making it much easier to perform batch operations. Pyxplot is available for free download under the GNU GPL The GNU General Public License (GNU GPL or simply GPL) is a series of widely used free software licenses that guarantee end users the four freedoms to run, study, share, and modify the software. The license was the first copyleft for general us .... Mathematical environment Pyxplot's mathematical environment is unusual in that numerical variables can have physical units.

Conchospiral
In mathematics, a conchospiral a specific type of space spiral on the surface of a cone (a '' conical spiral''), whose floor projection is a logarithmic spiral. Conchospirals are used in biology for modelling snail shells, and flight paths of insects and in electrical engineering for the construction of antennas. Parameterization In cylindrical coordinates, the conchospiral is described by the parametric equations: :r=\mu^t a :\theta=t :z=\mu^t c. The projection of a conchospiral on the (r,\theta) plane is a logarithmic spiral. The parameter \mu controls the opening angle of the projected spiral, while the parameter c controls the slope of the cone on which the curve lies. History The name "conchospiral" was given to these curves by 19th-century German mineralogist Georg Amadeus Carl Friedrich Naumann, in his study of the shapes of sea shells. Applications The conchospiral has been used in the design for radio antenna In radio engineering, an antenna or aerial is the int ...

Perl
Perl is a family of two high-level, general-purpose, interpreted, dynamic programming languages. "Perl" refers to Perl 5, but from 2000 to 2019 it also referred to its redesigned "sister language", Perl 6, before the latter's name was officially changed to Raku in October 2019. Though Perl is not officially an acronym, there are various backronyms in use, including "Practical Extraction and Reporting Language". Perl was developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. Raku, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. Both languages continue to be developed independently by different development teams and liberally borrow ideas from each other. The Perl languages borrow features from other programming languages including C, sh, AWK, and sed; They provide text processing facilities without the arbitrary data-le ...

GNU Octave
GNU Octave is a high-level programming language primarily intended for scientific computing and numerical computation. Octave helps in solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with MATLAB. It may also be used as a batch-oriented language. As part of the GNU Project, it is free software under the terms of the GNU General Public License. History The project was conceived around 1988. At first it was intended to be a companion to a chemical reactor design course. Full development was started by John W. Eaton in 1992. The first alpha release dates back to 4 January 1993 and on 17 February 1994 version 1.0 was released. Version 7.1.0 was released on Apr 6, 2022. The program is named after Octave Levenspiel, a former professor of the principal author. Levenspiel was known for his ability to perform quick back-of-the-envelope calculations.
