Reference Manual
This project is a fork of Thomas M. Hermann's linear-algebra system. We chose it as the basis for Lisp-Stat's linear algebra because it uses high-quality algorithms, has extensive references and good test coverage.
To get a local copy up and running follow these steps:
An ANSI Common Lisp implementation. Developed and tested with SBCL.
Lisp-Stat is composed of several system that are designed to be
independently useful. So you can, for example, use linear-algebra for
any project needing to manipulate two dimensional data in a machine
learning or statistical setting.
To make the system accessible to ASDF (a build facility, similar to make in the C world), clone the repository in a directory ASDF knows about. By default the common-lisp directory in your home directory is known. Create this if it doesn't already exist and then:
- Clone the repositories
cd ~/common-lisp && \
git clone https://github.com/Lisp-Stat/linear-algebra.git- Reset the ASDF source-registry to find the new system (from the REPL)
(asdf:clear-source-registry) - Load the system
(asdf:load-system :linear-algebra)
If you have installed the slime ASDF extensions, you can invoke this with a comma (',') from the slime REPL in emacs.
To get the third party systems that Lisp-Stat depends on you can use a dependency manager, such as Quicklisp or CLPM Once installed, get the dependencies with either of:
(clpm-client:sync :sources "clpi") ;sources may vary(ql:quickload :linear-algebra)You need do this only once. After obtaining the dependencies, you can
load the system with ASDF as described above without first syncing
sources.
linear-algebra is in a usable state for pure lisp operations. Future plans include:
- Merging functionality from numerical-utilities where there is duplication
- Add a backend for CUDA for GPU based linear algebra operations
- Improve documentation
See the open issues for a list of proposed features (and known issues).
This system is part of the Lisp-Stat project; that should be your first stop for information. Also see the resources and community page for more information.
