MatrixDotBench

A simple benchmark of some strategies to do Matrix multiplication (dot product) in Ruby.

See post at: http://abinoam.tl1n.com/400x-faster-matrix-multiplication-for-ruby/

Basically it shows that using NMatrix#dot with an NMatrix object with dtype: :float64 is more than 400x faster than using Matrix#*.

Installation

$ git clone git@github.com:abinoam/matrix_dot_bench.git
$ cd matrix_dot_bench
$ bundle install

Usage
