数值分析

author: Katyusha

帮助理解算法的一套数值分析工具库,代码未经优化,仅供学习

已经移除了自定义的矩阵运算工具Sprase,转为使用Eigen Eigen的使用详见官网:http://eigen.tuxfamily.org/index.php?title=Main_Page

结构如下:

  • Numerical:数值运算

    • 基础数据结构:
      • 区间(只允许是整型/浮点类型)Interval
      • 分段函数SegmentFunction
    • 算法:
      • 三次样条插值法CubicSplineInterpolation
      • 龙贝格积分法RombergIntegration
      • 最优平方逼近(最小二乘法)LeastSquareFitting/MutliLinearLeastSquareFitting
      • 最优一致逼近(Remes算法)BestUniformApproximation
  • Symbolic:符号数学工具

    • 基础数据结构:
      • 表达式树ExprTree
  • Optimalize:优化求解工具

    • 基础数据结构:
      • NULL
    • 算法:
      • LP(等式约束)-原始对偶内点法
      • LP(不等式约束)-障碍函数内点法
      • QP(无约束)-共轭梯度法
      • QP(等式约束)-拉格朗日法
      • QP(不等式约束)-有效集法
