These are some rough benchmarks to get an idea of the performance of math.js compared to other JavaScript libraries and to Octave (C++). They only give an indication of the order of magnitude difference meant to see were math.js has room for improvements, it's not a fully fletched benchmark suite.

How to run

JavaScript library benchmarks

Install the dependencies once:

npm install

run the tests:

node benchmark.js

Octave benchmarks

Open Octave, run the script benchmark_octave.m

To do

compare with python and Octave
use larger matrix, like 250x250 instead of 25x25
Compare expression parsers

evaluate the following function thousand times
```
f(x) = (sin(x) + cos(x/2)) * 5
```
Libraries:
