LU Decomposition

In Mathematica, the function LUDecomposition factors a matrix
m
into the form P L U, where P is a permutation matrix, L is a lower triangular matrix, and U is an upper triangular matrix. The decomposition fails for most matrices
m
with zero-valued minors, such as
0
1
1
0
0
0
0
1
0
, although P L U may be close to
m
.
