Numerical jacobian-based solver
WebIn numerical linear algebra, the Jacobi method (a.k.a. the Jacobi iteration method) is an iterative algorithm for determining the solutions of a strictly diagonally dominant system of linear equations. Each diagonal element is solved for, and an approximate value is plugged in. The process is then iterated until it converges. WebJacobian method or Jacobi method is one the iterative methods for approximating the solution of a system of n linear equations in n variables. The Jacobi iterative method is …
