C library for linear algebra
提问by Cartesius00
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.
请给我一些关于线性代数（矩阵代数、特征值、特征向量等）的高性能 C 库的提示。可以是开源的，也可以是闭源的。

EDITThanks to comments from osgx:
编辑感谢 osgx 的评论：
- 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 extremelygood though) and is used quite often; mostly because of its portability.
- CLAPACK 是引擎盖下使用非常高性能的 BLAS 库的库，其他库（如 ATLAS）也是如此。
- GSL 是一个独立的 C 库，不如任何基于 BLAS 的库快。不过其性能还是相当不错的（不是非常虽好），并使用相当频繁; 主要是因为它的便携性。
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.
我知道 LAPACK 和 GSL，我可以推荐它们。LAPACK 是非常低级的库，GSL 使用起来可能更舒服，但说到良好的性能——它是基于 BLAS 的库。

Again if you are actually looking/open for modern C++ code, Armadillois getting really hyped/popular. Also see their own benchmarkingagainst IT++and Newmat.
再说一次，如果您实际上正在寻找/打开现代 C++ 代码，Armadillo正变得非常大肆/流行。另请参阅他们自己针对IT++和Newmat的基准测试。
