Science and engineering should know the C + + Mathematical Computing Library

Science and engineering should know the C + + Mathematical Computing Library (RPM)

As a science and engineering student, the finite element analysis, numerical calculation, three-dimensional modeling, signal processing, performance analysis, simulation analysis ... These are more or less related to the software we commonly use, if one day you only need some very limited features of these large-scale software systems, do you want to use a few grams of software that frequently? In fact, I think if the system is not very large, not very complex, we are personally likely to write their own code to achieve these ' limited functions '. Do not think this is a very difficult thing, I always think that the C language learning during college is extremely useful, as long as you will basic C language grammar, you can.

Let me show you a few very useful math Library of c/s + +, they are basically open source, you do not have to worry about copyright issues, they are some free software, all you have to do is to carefully read their license agreement to ensure that do not abuse it:

Computational Geometry algorithm library Cgal
Cgal, the computational Geometry algorithm library, is a large C + + library of geometric data structures and algorithms, such as Delaunay triangular mesh, mesh generation, Boolean operations of polygons, and various geometric processing algorithms. Cgal is used in various fields: computer graphics, Scientific visualization, computer-aided design and modelling, geographic information systems, molecular biology, medical imaging, robotics and motion planning, and numerical methods.

Math Package Octave
Octave is a mathematical software package similar to MATLAB and Scilab, which can be used for various operations and programming. It also has a rich C + + interface that can be called when the user is programming. It plots using gnuplot.
The use of octave is also based on the character terminal pattern, and when drawing is required, the gnuplot is called for data plotting and is displayed.
Octave is written in C + +, and its rich library is also available for users to invoke when writing software. Octave Library in detail under/usr/share/doc/octave-2.1.50/liboctave, the file is Liboctave.dvi and requires a PDF file that can be run:
DVIPDFM Liboctave.dvi
Converts a DVI file to a PDF file.
Octave also supports the invocation of FORTRAN, GSL bindings and so on. Can be customized by the user's own functions, subroutines and so on.

Finite element analysis software Openfem
Finite element analysis, even if the finite element method is used to analyze static or dynamic objects or systems. In this method, an object or system is decomposed into a geometric model composed of several interconnected, simple, independent points. In this method, the number of these independent points is limited and is therefore called the finite element. The equilibrium equations deduced from the actual physical model are used at each point, resulting in a set of equations. This group of equations can be solved by means of linear algebra. The accuracy of finite element analysis cannot be increased infinitely. The accuracy of the solution is no longer improved after the number of yuan reaches a certain height, and only the calculation time is improved.

Finite element calculation framework Oofem
Oofem is an object-oriented architecture for open source Multiphysics parallel finite element programs. The purpose of this project is to provide efficient and powerful finite element computing tools, as well as to provide a highly modular and scalable development environment. Finite element analysis is usually done by computer software, the famous engineering software is: Msc.nastran, ADINA, Ls-dyna, ANSYS, ABAQUS, 2d-sigma and so on.

C + + Symbolic computing library Ginac
Ginac (Ginac is not a CAS computer algebra system) is a C + + library for symbolic computations. It is designed to allow integrated system creation, symbolic operations embedded with more sophisticated computer science (such as compute-intensive, graphical interface, etc.), digital application areas. In contrast to other cases, it does not attempt algebra to provide extensive functionality and simple programming language, but rather to accept a given language (C + +) and extend the algebraic function settings.

Partial differential Equation Solver toolbox DUNE(Windows systems are not currently supported)
DUNE (Distributed and Unified Numerics Environment), distributed and unified numerical solution environment, is a modular toolbox of grid-based methods (PDE) for solving partial differential equations. Dune is the first time that all these embody the concept of scientific computing from an abstract interface setting. Modern C + + programming techniques make the same concepts very different implementations using a very low overhead of a common interface. As a result, dune ensures efficiency in scientific computing and supports high-performance computing applications.

Almost all I know is this, in fact, this article mainly refers to the open source China community announced some projects, I do is just finishing up the present to everyone, hope to everyone in the future study, work help. Deep down inside, I actually really want to use a very good one day of this aspect of the domestic software, just do not know when. Don't want to take a pirated XP, office, pirated UG, pirated ansys, pirated GT, pirated AMESim, pirated matlab ... Originally my computer is full of pirated, sometimes think this is a kind of ridiculous things, but there is no way. Perhaps, from this moment on, we have a new idea, and the situation will be changed in a few years.
It's a lot of talk ...
