Efficient matrix math in erlang in the same spirit as NumPy.
An example of the potential future usage of the matrix module in NumErl.
matrix_demo.erl
-module(matrix_demo).
-export([do_it/0]).
do_it() ->
%% Matrix 3x3 full of ones
MyMatrix = matrix:ones(3),
%% Matrix 3x3 identity
Identity = matrix:identity(3),
%% Transposed ones matrix is in fact equal as expected.
MyMatrix = matrix:transpose(MyMatrix),
%% Identity multiplied by MyMatrix gives MyMatrix
MyMatrix = matrix:multiply(MyMatrix, Identity),
%% Convert MyMatrix to a tuple of tuples of numbers
TMatrix = matrix:to_tuples(MyMatrix),
%% Convert MyMatrix to a list of lists of numbers
LMatrix = matrix:to_lists(MyMatrix),
io:format("TMatrix ~p~n", [TMatrix]),
io:format("LMatrix ~p~n", [LMatrix]),
ok.
