Row Reduced Echelon Form of input matrix

Examples

>>> matrix = numpy.array([[1,0,0,1,0,0,1,0],
                          [0,1,1,1,0,0,0,1],
                          [1,1,1,0,1,0,0,0],
                          [1,0,0,1,0,1,0,1]], dtype=np.bool_)
>>> r = rref(matrix)
>>> r.astype(int)
array([[1, 0, 0, 1, 0, 0, 1, 0],
    [0, 1, 1, 1, 0, 0, 0, 1],
    [0, 0, 0, 0, 1, 0, 1, 1],
    [0, 0, 0, 0, 0, 1, 1, 1]])
