LU reduction, often referred to as LU decomposition, is a mathematical method used in linear algebra to factor a given square matrix \( A \) into the product of two matrices: a lower triangular matrix \( L \) and an upper triangular matrix \( U \). This can be expressed as: \[ A = LU \] ### Components: 1. **Lower Triangular Matrix (L)**: A matrix \( L \) where all the elements above the main diagonal are zero.
