%% Purpose: Simple example of NIFs using resource objects to implement functions
%%          for matrix calculations.

-module(matrix_nif).

-export([create/3, pos/3, add/2, size_of/1, to_term/1]).

-define(nif, nif_error(?LINE)). 

-on_load(on_load/0).

on_load() ->
    erlang:load_nif("./matrix_nif", 0).

%% NIFs
create(_Rows, _Cols, _RowList) -> ?nif.
pos(_Mx, _Row, _Col) -> ?nif.

size_of(_Mx) -> ?nif.
to_term(_Mx) -> ?nif.

nif_error(Line) ->
