A linear algebra library, written in TypeScript and accelerated with C++ bindings to BLAS and LAPACK.

Usage

Follow the installation instructions in nlapack and nblas to get maximum performance.

# with C++ bindings
$ npm install vectorious

# or, if you don't want C++ bindings
$ npm install vectorious --no-optional

import v = require('vectorious');

const x = v.random(2, 2);
