,Jacobi 迭代格式,第六节收敛性讨论/*On Convergence of Iterative methods*/,6 On Convergence of Iterative methods,2）矩阵形式：,3）迭代格式收敛条件,Jacobi 迭代格式,Gauss-Seidel 迭代格式,注：二种方法都存在收敛性问题。有例子表明：Gauss-Seidel法收敛时，Jacobi法可能不收敛；而Jacobi法收敛时，Gauss-Seidel法也可能不收敛。,6 On Convergence of Iterative methods,6 On Convergence of Iterative methods,6 On Convergence of Iterative methods,6 On Convergence of Iterative methods,6 On Convergence of Iterative methods,6 On Convergence of Iterative methods,6 On Convergence of Iterative methods,6 On Convergence of Iterative methods,6 On Convergence of Iterative methods,6 On Convergence of Iterative methods,6 On Convergence of Iterative methods,6 On Convergence of Iterative methods,6 On Convergence of Iterative methods,6 On Convergence of Iterative methods,本章重点总结,
