LU decomposition is a matrix factorization technique used in numerical linear algebra. It involves breaking down a square matrix \( A \) into the product of two matrices: a lower triangular matrix \( L \) and an upper triangular matrix \( U \).

An LU decomposition factors a matrix as a lower-triangular matrix times an upper-triangular matrix. It records Gaussian elimination so that multiple right-hand sides can be solved by forward and backward substitution.
