matlab无约束优化问题的信赖域算法程序(matlab trust region method)

修正单纯行方法，用于matlab优化设计。(The revised simplex-line method to for matlab optimize the design.)

this code is about mlp 1 layer neural network with back propagation training algorithm by using geradient descence for nonlinear system. input data are random.

This program is to plot 3-D radiation pattern of 2-element array antenna.

说明：  心电、脉搏信号的提取和处理，心电脉搏特征波提取(Extraction and Processing of ECG and Pulse Signal and Extraction of ECG Pulse Characteristic Wave)

用matlab实现的均值滤波函数，可以有3*3,5*5等多种窗口可选(Using matlab to achieve the mean filter function, can have 3* 3,5* 5 and many other window options)

This code perform the DCT and quantization on all the channels without any sub-sampling and for the compression of color images, they are first converted to the YCbCr color format and vice versa, use the function rgb2ycbcr and ycbcr2rgb.

说明：  基于信噪比的QAM星座图算法描述，有很多星座图的相关知识及仿真(SNR of the QAM constellation based on algorithm description, there are many constellation of knowledge and Simulation)

一个关于JEPG2000的MATLAB 源码，功能基本上可以实现 ，但也有一定的不足，希望大侠多多指教(one of the correctness of MATLAB source, the basic function can be achieved. But there are certain deficiencies, the exhibitions hope Shanhaiguan)

最小二乘拟合指数函数,自编程序，非常有用(Least squares fitting index function, the program is compiled, very useful)
