P is an n x 1 matrix the initial guess

WebbClearly, we performed m − 1 = n−1 2 row exchanges. Thus, for odd values of n, we need to perform n−1 2 row exchanges. If P is the permutation matrix with 1s on the reverse diagonal, then the rows of P are simply the rows of the identity matrix in precisely the reverse order. Thus, the above reasoning tells WebbJacobian 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 considered as an iterative algorithm which is used for determining the solutions for the system of linear equations in numerical linear algebra, which is diagonally dominant.In …
