Implementation of Transposition Cipher in C

matlab基础，压缩感知技术重建程序，matlab程序例程(compressive sensing)

说明：  shooting method for ODE

Mathcad skrypt.pdf

说明：  基于matlab 的信号处理方面的程序实现，包括幅频特性，滤波器的设计等(These are program examples about signal and system based on matlab )

edge detection and segmentation

在一个具有几个顶点的连通图G中，如果存在子图G 包含G中所有顶点和一部分边，且不形成回路，则称G 为图G的生成树，代价最小生成树则称为最小生成树(If there subgraph G ' contains all vertices in G, and part of the side, and does not form a loop, then G' in a few vertices connected graph G is the spanning tree of a graph G consideration of the minimum spanning tree is called minimum spanning tree)

说明：  实现直接序列扩频水印的嵌入与提取。基于待嵌入消息生成二进制水印序列,生成扩频码，用消息序列调制生成水印序列。依次处理灰度图像的每一个载体图像像素，根据相应位置 水印序列完成嵌入修改。(Realize the embedding and extraction of direct sequence spread spectrum watermark. The binary watermark sequence is generated based on the message to be embedded, the spread spectrum code is generated, and the watermark sequence is generated by message sequence modulation. Each carrier image pixel of gray image is processed in turn, and the embedding modification is completed according to the corresponding position watermark sequence.)

说明：  利用自相关函数估计基音周期，函数jiyinzhouqi，输入参数是分析语音文件名和帧移，帧移在5~10ms(use of the correlation function is estimated Pitch, jiyinzhouqi function, input parameters to analyze voice file names and frame shift, frame shift in the 5-10ms)

说明：  模糊pid算法的程序，还有图形截图，很有用，很详细(fuzzy pid)
