Jacobian iterative method is an earlier and simpler one among many iterative methods, and its name is also to commemorate the famous Prussian mathematician Jacobian. The calculation formula of Jacobian iteration method is simple, and the multiplication of matrix and vector only needs to be calculated once in each iteration, and the original matrix A remains unchanged during the calculation, so the calculation is easier.

pay attention to

Jacobian iteration method has obvious advantages and simple calculation formula. It only needs to calculate the multiplication of matrix and vector once per iteration, and the original matrix A remains unchanged during the calculation process, so it is easier to calculate in parallel. However, this iterative method is slow in convergence and takes up a lot of storage space, so it is not directly used in engineering, but an improved method.
