ArrayFire is a high performance library for parallel computing with an easy-to-use API. It enables users to write scientific computing code that is portable across CUDA, OpenCL and CPU devices. This project provides Lua bindings for the ArrayFire library. The wrapper is currently compliant with ArrayFire 3.2 API (and higher). If you find any bugs, please report them here.

TODO

Currently, tested only Windows with Lua 5.1.

• Progress being made on Linux and OSX with Lua 5.2 and 5.3

You can install ArrayFire using one of the following two ways.

• Download and install binaries
• Build and install from source

Post Installation Instructions

• Please read the wiki page for setting up the proper environment variables.

If you do not have the pre-installed library, use the source in arrayfire-lua/lua folder for building the libraries.

The following pre-processors need to be set when building lua.

- LUA_BUILD_AS_DLL
- CRT_SECURE_NO_WARNINGS

Use the visual studio project file present in src/Lua/arrayfire to build the library.

Use the cmake file in src/Lua/arrayfire to build the library.

• Ensure ArrayFire_DIR points to /path/to/arrayfire/share/ArrayFire/cmake

$ export LUA_PATH="/path/to/arrayfire-lua/lib/?.lua;;"
$ export LUA_CPATH="/path/to/arrayfire-lua/src/Lua/arrayfire/build/?.so;;"
$ lua helloworld/helloworld.lua

Currently segfaults on Linux. Untested on OSX.

This is a work in progress and is not intended for production use.

This project began with significant contributions from Steven Johnson. It is currently being maintained by @arrayfire/lua-devel team.
