平均因子分解法，适用于正定矩阵First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X=U U, where U is the square root matrix of X, and satisfies: (1) U U = X (2) U is upper triangular (that is, it has all zeros below the diagonal). It seems that the assumption of positive definiteness is necessary. Actually, it is "positive definite" which guarantees the existence of such kind of decomposition. -Average factor decomposition method applied to positive definite matrix First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X = UU, where U is the square root matrix of X, and satisfies: (1) UU = X (2) U is upper triangular (that is, it has all zeros below the diagonal).

C++链表操作，从创建一个链表到对链表的增删改查，适合初学算法的朋友学习参考，转自别处，对其进行了一些修改。

16： 00傅里叶算法，采用标准C语言，优化计算速度，比传统算法快得多

一个有关进制的和程序，它将一定范围内的数编制成组，通过从二进位制到十进位制， 进行编组，输入进制数和组数，即可自动计算出数据，并显示在屏幕上，同时输出到文件中，是很不错的程序，我用了好几天才编好，很精悍！-one of the 229 and procedures, it would certainly within the scope of the report into several groups, By binary system to the decimal system, organization, and the importation of 229 for a group, they will automatically calculate data, displayed on the screen, while the output to a file, is a very good procedure, I spent several days prepared and very lean!

常用数值算法大全，包扩各种算法，大家共享-Numerical algorithm used Daquan, including widening of various algorithms, everyone shared

在该算法中，我们使用语言 php 翻译难题 8，8 的谜题是用来考验智力的经典问题之一.在这里是多么经典 8 的难题，看起来像在一个 3 X 3 盒子里所有的盒子都充满了号码从 1 到 8，除了一个盒子可以移动的空白，以左、 右、 上和下。 在初始状态数是不可排序、 处于最终状态的数字进行排序。我们的目标是找出移动这种空白状态的序列达到了这一最终目标。在这个问题中我们尝试用广度优先搜索来解决它。我们用特别 Que 在 PHP 中可用来存储难题的国家。作为初始状态变得无序，如果它需要若干步骤来达到目标状态，它会采取大量内存和可能超出您的 PHP 限制。试着保持像记忆一样可能在 PHP 中这里是在 8 的难题实现广度优先搜索的 PHP 代码。

分形几何被曼德勃罗喻为是大自然的几何学。这个代码，采用了分形几何的方法模拟生成自然界的云。形象而逼真。-Mandelbrot fractal geometry has been described as the geometry of nature. The code, adopted the method of fractal geometry of nature cloud simulation. Realistic image.

本程序是用纯C语言编的一个基于命令行的四则运算计算器。主要用于计算四则运算表达式的值，同时可以实现四种进制任意两种之间的转换。 主要功能：1.四则运算：能够解释并执行四则运算表达式。四则运算就是包含+、―、*、/、.（小数点）和数字的运算表达式，例如：3+2.9*（5-6/3） -4+（+8*6）等； 2.错误警告：能够对不符合语法的表达式给出相应的错误警告,本程序共给出了8大类警告 3.进制转换：能够做二进制、八进制、十进制、十六进制中任意两种进制之间的互相转换 4.帮助系统：提供完善的帮助系统 5.出错保护：有良好的出错保护系统，命令行输入错误，程序仍能正常运行。-this program is pure C-language series based on a command line of four Operational calculator. Mainly used in the calculation of four computing the value of the expression, and can achieve four band arbitrary conversion between the two. The main functions : 1. Four computing : the ability to interpret and apply the four Operational expression. Four operations is included ,-,*,/,.( decimal point) and digital arithmetic expressions, for example : 2.9* 3 (5-6/3)-4 (8* 6); 2. Wrong warning : to be able to not grammar of expressions is the corresponding error warnings, the procedure is a total of eight major categories of warning 3. Decimal Conversions : can do binary, octal, decimal, hexadecimal arbitrary b
