WebFeb 12, 2024 · Cholesky Factorization; QR Factorization; Suppose we wish to solve a problem \(Ax=b\), where \(A,b\) are known. Each row of \(A\) and \(b\) represents a linear equation, so the problem represents a system of linear equations. This is one of the most well-studied problems in mathematics. WebJul 20, 2024 · The given system of equations is A X = C. We substitute A = L U. Thus, we have L U X = C. We put Z = U X, where Z is a matrix or artificial variables and solve for L Z = C first and then solve for U X = Z to find X or the values of the variables, which was required. Example: Solve the following system of equations using LU Decomposition method:
