Scientific libraries for Lua? [closed]

Are there any scientific packages for Lua comparable to Scipy?

There is the basis for one in Numeric Lua.

What about a plotting library for Lua? – Ambi 4/10, 2017 at 12:15

I wrote a Lua wrapper for Dislin for Lua 5.1, but there are probably better options today. A Google search for "lua plot" shows a few options: lua-gnuplot, Torch, and lua_flot. – Vitellus 4/10, 2017 at 14:50

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.

While Torch7 is for general use, currently most of the work has been done for neural networks. Also, while it does support gnuplot, there isn't anything like matplotlib for it. I use Torch7, but still go back to Python for analysis and plotting. Hopefully that can change. – Glorious 24/6, 2012 at 5:58

Also not officially supported on Windows? – Kiser 29/6, 2013 at 2:30

there is github.com/facebook/iTorch which uses ipython plotting backed – Inkblot 28/2, 2015 at 0:25

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

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

And also, you could try lutorpy for converting between lua/torch and numpy array, so you can use scipy with torch. – Calandra 30/5, 2016 at 8:53

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.

Numeric Lua is deprecated in favour of torch7 – Inkblot 28/2, 2015 at 0:23

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.

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.
