Preface - Cornell University
look at how inverse matrices and LU-Decompositions can help with the solution process. We’ll also take a look at a couple of other ideas in the solution of systems of equations. Systems of Equations Let’s start off this section with the definition of a linear equation. Here are a couple of examples of linear equations. 12 5 6810 3 7 1 9
