@tr1ckyf0x following the pull request #3 it seems that the multiplication between matrices does not give correct values.

// for example
let first: Matrix = [[0.4124564, 0.3575761, 0.1804375],
                          [0.2126729, 0.7151522, 0.0721750],
                          [0.0193339, 0.1191920, 0.9503041]]
let second: Matrix = [[1.0, 2.0, 3.0], [3.0, 4.0, 5.0], [5.0, 6.0, 7.0]]
print(a * mm)

The output is

[[0.8958039000000001, 2.1454565, 3.1756998000000003], [2.1847303, 4.5292971, 5.581533], [3.4736567000000003, 6.9131377, 7.987366199999999]]

instead

[[2.3873722, 3.3378422, 4.2883122], [2.7190045, 3.7190046000000003, 4.7190047], [5.1284304, 6.2172604, 7.3060903999999995]]
