C libraries for mathematical matrix operations
提问by Joris Meys
I know there are some optimized algorithms around for all kind of matrix decompositions (QR decomposition, SVD,...), multiplications and the likes. Yet, I couldn't find a good overview. For C++, there is quite some useful information in this question, but I'm looking for those things in C.
我知道有一些针对各种矩阵分解（QR 分解、SVD 等）、乘法等的优化算法。然而，我找不到一个好的概述。对于 C++，这个问题中有很多有用的信息，但我正在寻找 C 中的那些东西。

You did not mention whether you wanted an open-source or a commercial software, so here is a list containing both:
你没有提到你想要开源软件还是商业软件，所以这里有一个包含两者的列表：
- GNU Scientific Library(GSL)
- Basic Linear Algebra Subprograms(BLAS)
- Meschach
- Numerical Algorithms Group(NAG)
There was also this previous questionon the subject.
之前也有关于这个主题的问题。

You might want to take a look at BLASand LAPACK. These are written in Fortran, but are callable from C, and are pretty much thestandard libraries of this type.
您可能想看看BLAS和LAPACK。它们是用 Fortran 编写的，但可以从 C 调用，并且几乎是这种类型的标准库。
Most serious linear algebra packages that I know of (MATLAB, Octave, NumPy) are built using these.
我所知道的大多数严肃的线性代数包（MATLAB、Octave、NumPy）都是使用这些构建的。

Perhaps GNU Scientific Library (GSL) would be of interest.
也许 GNU 科学图书馆 (GSL) 会感兴趣。
