病态方程组的运算-CSM Group Operational

也被称为阿基米德算法螺旋或螺旋。可以考虑作为一个简单的分形形态，表现出一种概念的尺度相似。

这是我用Des-encrypt来加密和反加密文本文件的例子，这是一个简单的示例代码，对所有聊天程序都非常重要

这是学校ACM程序设计大赛的题目,拿出来大家算是当练习-This is the School ACM Programming Contest topic out when everyone is practicing

适合数据，其中包含异常值使用许多不同的方法对椭圆大多数都基于：1 / 5 点多做适合2 选择最好的一个3 / 标记相4/抛光 (即改装到使用标准的最小二乘代数距离准则相)".

C语言数值计算中常用的函数，如sin(x),cos(x)的实现方式的源代码。-Codes for functions which are used frequently in numerical calculation ,such as sine function,cosine function, written in C language

程序只产生均值为0，方差为1的随机数，要产生均值为E,方差为D的随机数，只要随机数*D+E就可以了。高斯随机数程序还是带参数的，参数是用来描述正态分布的一个浮点数表。在执行程序时，先生成这个表（只做一次），而后就可以任意多次地执行高斯随机数产生程序了。使用C是为了保证通用性，如果有人觉得麻烦，可以用C++做个类，把这些东西都封装进去。另外，如果有人有兴趣，也可以把它修改成任意形式分布的连续随机数产生程序，修改非常简单，这里就不提示了。-procedures have only mean of 0 and variance for a random number to produce the mean E, D variance for the random number, as long as a few random E* D on it. Gaussian random process parameters or with the parameter is used to describe a normal distribution of the float table. In the implementation process, Mr. into the table (one-off), and you can repeatedly arbitrary implementation Gaussian random number generator proceedings. The use of C is to ensure commonality, if someone finds trouble, can be used to be a Class C, all these things into account Packaging. Also, if someone is interested, can you change the form of arbitrary distribution of continuous random number generator procedure is very simple changes, I will not be sacrificed as a result.

大数阶乘，能计算超大数的阶乘，算法简单易懂，采用数组存储计算结果！本算法也可以改进采用链表存储结果！-majority factorial, which calculates the number of super factorial, the algorithm is simple to understand and use storage arrays results! The algorithm also can be improved using Chain store results!

非线性方程组不能用消去和分解法进行求解，jacabi迭代和高斯迭代是最常用的两种迭代方法-Nonlinear equations can not be eliminated and the decomposition method to solve, jacabi iteration and Gauss iteration is the most commonly used two types of iterative methods
