An LU factorization of a matrix involves writing the given matrix as the product of a lower triangular matrix L which has the main diagonal consisting entirely of ones, and an upper triangular matrix U in the indicated order. This is the version discussed here but it is sometimes the case that the L has numbers other ...

To verify the constraint, i.e. check whether x is the projection of X, one can use the relation

A square matrix is called lower triangular if all the entries above the main diagonal are zero. Similarly, a square matrix is called upper triangular if all the entries below the main diagonal are zero.
