雅克比迭代法就是众多迭代法中比较早且较简单的一种，其命名也是为纪念普鲁士著名数学家雅可比。雅克比迭代法的计算公式简单，每迭代一次只需计算一次矩阵和向量的乘法，且计算过程中原始矩阵A始终不变，比较容易并行计算。(The jacobian iteration method is one of the earlier and simpler iteration methods, which is also named in honor of the famous Prussian mathematician jacoby. The calculation formula of jacobian iterative method is simple. Every iteration only needs to calculate the matrix and vector multiplication once, and the original matrix A is always the same in the calculation process, which is easier to calculate in parallel.)
