中文版:高斯-赛德尔迭代计算器
原理:高斯-赛德尔与雅可比的迭代格式相同,唯一区别是算到第 i 个分量时立刻使用本轮已更新的 x₁ 到 xᵢ₋₁;信息传播更快,对称正定或对角占优矩阵上通常比雅可比少一半左右的迭代轮数。
步骤:① 输入系数矩阵与右端向量;② 点击求解;③ 对比轮数——同一题雅可比约需两倍轮数。
示例:A = [[4, 1, 0], [1, 5, 1], [0, 1, 4]]、b = [6, 14, 14] 时高斯-赛德尔 13 轮收敛到 10⁻¹⁰,雅可比需要 23 轮;两者都收敛到精确解 [1, 2, 3]。
注意事项:必须用新值这一特性使计算严格串行,不能像雅可比那样直接并行;对称正定阵上恒收敛,但对一般对角占优阵也存在雅可比收敛而高斯-赛德尔发散的反例,交付前用残差确认。
