含参Jacobi迭代的一个加速

Acceleration of Jacobi Method with Parameters

文章运用预条件得到含参Jacobi迭代的一个加速,并给出比较定理,最后通过数值例子验证了这个预条件含参Jacobi迭代有更好的收敛效果.

To give a special preeonditioner for the Jacobi method, and then get a comparison theorem. A numerical example is given in the sequel which shows that the preconditioner has a better convergence speed.
