C库为线性代数 [英] C library for linear algebra

问题描述

请，给我一个高性能的C库为线性代数（矩阵代数，特征值，特征向量等）的一些技巧。既可以是开源还是闭源。

解决方案

1. CLAPACK（f2c'ed LAPACK版本）


2. GSL - GNU科学图书馆

修改感谢来自osgx评论：

• CLAPACK是乌德引擎盖使用非常高性能的​​BLAS库，做其他的库，例如ATLAS库。


• GSL是一个独立的C库，没有那么快，因为任何基于BLAS。不过其性能还是相当不错的（不是的非常的虽好），并用于经常;主要是因为它的便携性。

我知道LAPACK和GSL和我都可以推荐他们两个。 LAPACK是非常低级的库和GSL可能是使用更舒适，但性能好说话 - 基于BLAS库是

Please, give me some tips for a HIGH PERFORMANCE C library for linear algebra (matrix algebra, eigenvalues, eigenvectors etc.). Can be both open-source or closed-source.

解决方案

1. CLAPACK (f2c'ed version of LAPACK)
2. GSL - GNU Scientific Library

EDIT Thanks to comments from osgx:

• CLAPACK is the library which uder the hood uses very high-performance BLAS library, as do other libraries, like ATLAS.
• GSL is a standalone C library, not as fast as any based on BLAS. However its performance is still quite good (not extremely good though) and is used quite often; mostly because of its portability.

I know both LAPACK and GSL and I can recommend both of them. LAPACK is very low-level library and GSL may be more comfortable to use, but speaking of good performance -- BLAS-based library it is.
