About SciRuby

SciRuby is a project focused on Ruby tools for scientific computing and data visualization. Its site presents a manifesto explaining Ruby's role in science, along with project status updates, documentation links, and ways to contact the community.

The site describes NMatrix, a linear algebra library with dense and sparse matrix storage, and MDArray for continued linear algebra work. It also lists experimental plotting libraries such as Rubyvis, Plotrb, and Nyaplot, plus work on Gnuplot APIs. Other areas mentioned include machine learning, linear mixed modelling, and tensor support. Visitors can find installation instructions, NMatrix documentation, recent blog posts, and links to GitHub issue trackers.

SciRuby suits Ruby programmers, students, and researchers who want to write scientific or visualization code in Ruby, and developers who want to contribute to open libraries.
