C ++ has a wide range of scientific computing libraries)

In C ++, the database status is very high. Mr. Bjarne stroustrup, father of C ++, has repeatedly said that designing libraries to Expand functions is better than designing more syntaxes. In reality, C ++ has a wide variety of database categories and has a wide range of solutions, from lightweight to heavyweight. Many of them are the masterpiece of thinking that opens your eyes or sighs with hope. Because the number of databases is very large and limited to the author's level, many of them do not know. Therefore, some libraries mentioned in this article are well-known large databases.
Introduction of C ++ major libraries -- Scientific Computing

1. Blitz ++

Reference: http://www.oonumerics.org/blitz

Blitz ++ is an efficient function library for numerical computing. It is designed to create a set of computing environments that are as convenient as C ++ and faster than FORTRAN. Usually, the value written in C ++ProgramIt is about 20% slower than Fortran, so blitz ++ just wants to get rid of this shortcoming. The method is to use the C ++ template technology to execute programs faster than FORTRAN.

Blitz ++ is still developing. It is not available for common Linear Algebra methods such as SVD, FFTS, and qmres, however, the user can easily use the functions provided by blitz ++ to construct the function.

2. pooma

Pooma is a free high-performance C ++ library for processing parallel scientific computing. Pooma's object-oriented design facilitates rapid Program Development and optimizes parallel machines to achieve the highest efficiency, making it easy to use in industrial and research environments.

3. MTL

Reference: http://www.osl.iu.edu/research/mtl

Matrix Template Library (MTL) is a high-performance generic component library that provides a large number of linear algebra functions for various format matrices. When some applications use high-performance compilers, such as Intel compilersCodeIt can be seen that the efficiency is almost the same as that of handwriting.

4. cgal

Blitz ++
Software name blitz ++ (incompatible with the vc6 compiler)
Resource Web site http://sourceforge.net/project/showfiles.php? Group_id = 63961
Function overview the current versions provide dense arrays and vectors, random number generators, and small vectors and matrices. it is an efficient numeric computing function library designed to build a convenient and faster numeric computing environment like C ++. Generally, the numerical program written in C ++ is about 20% slower than that written in FORTRAN. Therefore, blitz ++ just wants to get rid of this shortcoming. The method is to use the C ++ template technology to execute programs faster than FORTRAN.

MTL
Software name Matrix Template Library (compatible with vc6 compiler)
Resource Web http://www.osl.iu.edu/research/mtl/
Function Overview The Matrix Template Library (MTL) is a high-performance generic component library that provides comprehensive linear algebra functionality for a wide variety of matrix formats. MTL focuses on Linear Algebra-related computing tasks, such as matrix generation (diagonal, bounded, sparse, symmetric, etc.), related computing, transformation, and operations on one-dimensional vectors.
