集中度、集中期分析 matlab代码 用于降水、径流分析(precipitation concentration degree (PCD) )

CRD编程系列软件；它以功能强大、操作简单、实用性强、自动化程度高等特点(CRD series programming software it is powerful, simple, practical, high degree of automation)

LYAPACK is a MATLAB toolbox for the solution of certain large scale problems in control theory, which are closely related to Lyapunov equations. In contrast to the lyap and dlyap command in the MATLAB Control toolbox it uses iterative algorithms and is intended for large, sparse problems.

数字图像处理中 灰度处理函数 如果有需要的请下载 谢谢了 (Gray-scale digital image processing function to)

借鉴了主成分分析算法（PCA），IMC-PID是利用内模控制原理来对PID参数进行计算，数据模型归一化，模态振动。( It draws on principal component analysis algorithm (PCA), The IMC- PID is using the internal model control principle for PID parameters is calculated, Normalized data model, modal vibration.)

Simple face and eye detection MATLAB Release: R13 You can use this codes for face detection based on color segmentation and eye region detection.

A matlab code for abtaining th band structure by using PWE method

选择两张图片，一张水印图，一张嵌入图，将水印图进行Arnold置乱算法将其置乱，嵌入到嵌入图中，形成数字零水印，选用白噪声、高斯低通滤波、压缩、剪切、旋转攻击测试。以此观察图像鲁棒性(Select two pictures, a watermark and an embedded graph. We will scramble the watermark image with Arnold scrambling algorithm and embed it into the embedded map to form digital zero watermark. We choose white noise, Gauss low pass filtering, compression, shearing and rotation attack test. To observe the robustness of the image)
