Incorrect order for upper and lower. For lower (i>j), for upper (j>i), not vice vera as he specified.

I believe the code is inaccurate for the lower and upper matrices. All the program did was cancel out any terms above and below the main diagonal respectively. There is no elimination in either of the matrices and we can see that by multiplying L and U together where we do NOT return to the original matrix. The correct lower matrix should be [[1, 0, 0], [4, 1, 0], [7, 2, 1]] while the upper matrix should be [[1, 2, 3], [0, -3, -6], [0, 0, 0]].

Incorrect method. The input are output matrix are not equivalent. They're two different matrices. 00:57

The lower and upper matrices are not equivalent to the input matrix this is just wiping out the lower or upper tingle with zeros
