用高斯-赛德尔迭代法求方程组的根。它的原理与简单迭代法相似，但在赛德尔迭代法中，每次迭代时充分利用当前最新的迭代值-With the Gauss- Seidel iterative method seeking the roots of equations. Its principle with simple iterative method similar, but the Seidel iteration method in each iteration to take full advantage of the current value of the latest iteration
