“…Direct methods, such as LU (Lower-Upper triangular) factorization, Gaussian elimination, QR factorization, and Cholesky factorization, are typically employed for dense linear systems, that is, systems that have the majority of their elements as non-zero values. In contrast, iterative methods encompass techniques such as Jacobi, Gauss-Seidel, and relaxation iterations, which are effective for sparse linear systems [22]. This present work solves the system of equations using Gaussian elimination with partial pivoting, which is the method adopted by the VTM software.…”
