Numeric Javascript

Numeric Javascript is presented as a JavaScript library for sophisticated numerical computation in the browser and elsewhere. The page highlights example areas such as linear algebra, complex numbers, splines, ODE solving, unconstrained optimization, and PDEs with sparse linear algebra.

The site also describes a Workshop for writing and sharing worksheets of JavaScript commands, with plotting support through Flot. It notes performance benchmarks, automated unit tests in several browsers, a Google Group for discussion, and a public GitHub repository.

Reading notes

#

• The library performs numerical computations in pure JavaScript in the browser and elsewhere.
• The page points to blog posts about faster linear programming, sparse matrices in column compressed storage, and Linear Programming in Numeric Javascript v1.2.
• The Workshop is a JavaScript console for experimenting with Numeric Javascript through worksheets.
• Worksheets can be saved and shared by permanent link.
• The Workshop includes plotting facilities using Flot.
• The site says the library is tuned for the best possible performance for JavaScript.
• A benchmark compares Numeric with Sylvester and Google Closure’s Matrix object.
• Numeric Javascript includes unit tests that run automatically in several browsers.
• A report generated from those tests is available.
• The community page links to a Google Group and a public GitHub repository.
• The author is Sébastien Loisel.
