三次样条插值c++头文件，一些头文件，非常好(Cubic spline interpolation c++ header files, some header files)

计算偏心圆导热计算以及同位网格上的SIMPLE算法 (Calculating thermal calculations and eccentric position on the grid with SIMPLE algorithm)

矩阵转换问题 行与列的个数均为n 的矩阵称为n 阶方阵。假定矩阵中的每个元素的值在0到9之间，则可以将矩阵中的所有元素按行依次排列得到一个“单行矩阵字符串”。(Matrix conversion, the number of rows and columns of the matrix n are called n-order square. Assume that each element of matrix value in the 0 to 9, you can press all the elements of the matrix rows in order of priority for a " single matrix string." )
