高斯赛德尔迭代它是数值分析重的经典的算法，我在这儿把我自己写的程序给大家分享。--high resistivity iterative numerical analysis it is important to the classical algorithm, I have been here my own written procedures to share with you all. -

用Visual C++实现的高斯—赛德尔迭代法 很好用的(With Visual c + + implementation of gauss - seidel iterative method is very useful)
