Scientific libraries for Lua? [closed]

Question

Are there any scientific packages for Lua comparable to Scipy?

Answer 1

There is the basis for one in Numeric Lua.

Answer 2

You should try Torch7 (github).

Torch7 has a very nice and efficient vector/matrix/tensor numerical library with a Lua front-end. It also has a bunch of functions for computer vision and machine learning.

It's pretty recent but getting better quickly.

Answer 3

One can always use Lunatic Python and access scipy inside lua.

> require("python")
> numpy = python.import("numpy")
> numpy.array ... etc ..

Answer 4

You have some options:

• Numeric Lua - C module for Lua 5.1/5.2, provides matrices, FFT, complex numbers and others
• GSL Shell - Modification of Lua (supports Lua libraries) with a nice syntax. Provides almost everything that Numeric Lua does, plus ODE solvers, plotting capabilities, and other nice things. Has a great documentation.
• SciLua - Pure LuaJIT module. Aims to be a complete framework for scientific computing in Lua. Provides vectors and matrices, random numbers / distributions, optimization, others. Still in early development.
• Lua Numerical Algorithms - Pure LuaJIT module (uses blas/lapack via LuaJIT FFI). Provides matrices / linear algebra, FFT, complex numbers, optimization algorithms, ODE solver, basic statistics (+ PCA, LDA), and others. Still in early development, but has a somewhat complete documentation and test suits.

Answer 5

I'm not sure if it is comparable to Scipy, but there is GSL Shell which is based on LuaJIT and GNU Scientific Library, which offers many numerical algorithms and vector/matrix linear algebra operations.

Answer 6

There's a Numpy-like extension for Lua which runs without dependencies at

https://github.com/jzrake/lunum

In the future it will provide FFT's and linear algebra like Numpy+Scipy. Presently it supports numeric array manipulation like in Numpy.
