Erlang Matrix Functions via eRserve

This is an Erlang matrix library that runs on top of R

Prerequisites

For Ubuntu users, eRserve can install through apt. This will start the daemon automatically.

> sudo apt install r-cran-rserve

Alternatively, the rserve library is available from CRAN. In an R shell, start the Rserve in daemon mode

> install.packages('Rserve')
> library(Rserve)
> Rserve()

Either way, the app expects reserve to respond on port 6311

Installation

Then, install the erserve.git

> rebar get-deps

Then, in the top directory, compile using rebar

> rebar compile

Usage

Only two functions are supported, transpose/1 and multiply/2

>  erl -pa ebin -pa deps/erserve/ebin/ -eval "application:start(matrix_erserve)"
