``numpy.linalg`` | |
================ | |
The NumPy linear algebra functions rely on BLAS and LAPACK to provide efficient | |
low level implementations of standard linear algebra algorithms. Those | |
libraries may be provided by NumPy itself using C versions of a subset of their | |
reference implementations but, when possible, highly optimized libraries that | |
take advantage of specialized processor functionality are preferred. Examples | |
of such libraries are OpenBLAS, MKL (TM), and ATLAS. Because those libraries | |
are multithreaded and processor dependent, environmental variables and external | |
packages such as threadpoolctl may be needed to control the number of threads | |
or specify the processor architecture. | |
- OpenBLAS: https://www.openblas.net/ | |
- threadpoolctl: https://github.com/joblib/threadpoolctl | |
Please note that the most-used linear algebra functions in NumPy are present in | |
the main ``numpy`` namespace rather than in ``numpy.linalg``. There are: | |
``dot``, ``vdot``, ``inner``, ``outer``, ``matmul``, ``tensordot``, ``einsum``, | |
``einsum_path`` and ``kron``. | |
