统计一个txt文件中字符的个数和单词的个数 可以指定文本文件中搜索指定字符-a txt document the number of characters and words can specify the number of text files to search for the designated characters

分数阶傅里叶变换作为傅里叶变换的广义形式,对LFM信号具有很好的能量聚集性, 时域和频域均可看作FRFT域的特例。LFM信号在不同变换域上的投影如图2所示, 可以看出LFM信号的能量分布于很宽的频域范围内, 而在适当的分数阶傅里叶域中是一个冲击函数。同时FRFT又是线性变换

学习VC的时候写的，求解有向图的最大流和最小截集。-learning to write when the solution is to map the maximum flow and minimum cut-set.

在labview自己打包的一个小程序，可以实现角度的正弦余弦计算，从而补充了lv中只有弧度计算的小缺憾。

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).

这个压缩程序包含了RGB转YUV以及YUV转RGB 配套的程序，经过验证，色彩不在对比的情况下是难于分辨的。

 比较详尽的GEP的python版本，包括了GEP常用的算法实现。GEP算法的基本过程和GA的过程非常相似，GEP处理的对象可以是单基因或多基因组成的染色体（基因组）。基因由线性的、固定长度的符号串组成。

本源代码详细编出多种格式求解对流扩散方程的源代码，非常有用，对求解对流扩散问题有很大帮助，并且代码都有详细的中文注解，简单易懂，对于编程能力不是很好的同学有很大帮助。
