nonlinear

This book is a short, focused introduction to MATLAB, a comprehensive software system for mathematics and technical computing. It will be useful to bothbeginning and experienced users.

用matlab显示图片的RGB各分量的灰度值(Matlab display images with the RGB values of the various components of the gray)

在一个图像块中调整两个(或多个) DCT系数的相对大小。将描述一个使用数字图像作为载体的系统。在编码处理中，发送者将载体图像分成8×8的像素块，每一块只精确地编码一个秘密信息位。嵌入过程开始时，首先伪随机地选择一个图像块bi，用它对第i个消息比特进行编码。令Bi=D{bi}为DCT变换后的图像块。 在通信开始前，发送者和接收者必须对嵌入过程中使用的两个DCT系数的位置达成一致，让我们用(u1,v1)和(u2,v2)来表示这两个索引。这两个系数应该相应于余弦变换的中频，确保信息保存在信号的重要部位(从而使嵌入信息不容易因JPEG压缩而完全丢失 (abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwx)

说明：  非平稳信号的一些处理函数，包括计算瞬时频率和群延迟及非平稳信号的生成。(Some non-stationary signal processing functions, including the calculation of the instantaneous frequency and group delay and non-stationary signal generation.)

说明：  GUI matlab 数字滤波器图形化设计 包含使用说明和设计报告、ppt(GUI matlab digital filter design graphic design report contains usage instructions and, ppt)

Buck and boost converter simply modified

matlab中大部分算法集中在里面，包括常用算法的重写等等，较为实用(matlab Most algorithms concentrated on the inside, including the rewrite of the common algorithms more practical)

一种新颖的区域生长方法，对传统的区域生长方法做了一定的改进，效果还不错。(A novel region growing method, the traditional region growing to do some improvements, the results were good.)

The function conload takes a dataset and a model (PCA, PLS, PARAFAC etc.) and calculates congruence loadings which is the extension of correlation loadings to uncentered and multi-way models(The function takes a dataset and a m odel (PCA, PLS, B6 etc.) and calculates congruence loadi ngs which is the extension of correlation loadi ngs to uncentered and multi-way models)

读取地震数据并画图显示，其中可以判断是工作站格式还是微机格式(Read seismic data and drawing display, which can be judged workstation format or computer format)
