椭圆曲线密码体制中的ECC校验验算法分析和程序实现可直接使用。 (The inspection algorithm analysis and procedures of the elliptic curve cryptosystem ECC can be used directly.)

//最小二乘法直线拟合 m_FoldList为关键点(x,y)的链表 拟合直线方程(Y=kX+b) (//linear least squares fitting m_FoldList as the key point (x, y) of Chain fitting linear equation (Y = C/56 b))

说明：  最小二乘法拟合曲线的一个小程序，采用C++程序，(Least-squares fitting curve C++ program)

圆面上的点到圆心的距离 圆面上的点到圆心的距离 圆面上的点到圆心的距离 圆面上的点到圆心的距离(Round surface of the distance from point to circle center point of the surface of the distance to the center circle to the center point of the surface of the distance from the surface point to the center circle distance)

四阶龙格库塔法，用C++编写，很有参考价值(Fourth-order Runge-Kutta method, written in C, a good reference)

根据输入的长宽，计算Rectangle面积周长等功能，并画出在txt文件中(Rectangle Create a class Rectangle with attributes length and width, each of which defaults to 1 a. Provide member functions that calculate the perimeter and the area of the rectangle. b. Also provide set and get functions for the length and width attributes. The set functions should verify that length and width are each integer numbers larger than 0 and less than 20. c. Write draw function to display the Rectangle: in Assignment1. ) d. Write a driver program to test class Rectangle.)

编写求取下述矩阵四叉树四进制M码和十进制码程序，并将运算结果返回。 1, 1, 1, 1, 2, 2, 3, 3, 1, 1, 1, 1, 2, 2, 3, 3, 1, 1, 1, 1, 4, 4, 5, 5, 1, 1, 1, 1, 4, 4, 5, 5, 6, 6, 7, 8,13,13,14,14, 6, 6, 9,10,13,13,14,14, 11,11,12,12,15,16,19,19, 11,11,12,12,17,18,19,19 (Prepared to strike the following matrix quadtree quaternary M code decimal code and procedures, and the operation result returned. 1, 1, 1, 1, 2, 2, 3, 3, 1, 1, 1, 1, 2, 2, 3, 3, 1, 1, 1, 1, 4, 4, 5, 5, 1, 1, 1, 1, 4, 4, 5, 5, 6, 6, 7, 8,13,13,14,14, 6, 6, 9,10,13,13,14,14, 11, 11, 12,12,15,16,19,19, 11,11,12,12,17,18,19,19)

二分法，用于多项式求解，迭代12次能达到很高的精度(Dichotomy for polynomial solving, iterative 12 times to achieve high precision)
