用传输矩阵的方法和Matlab技术研究光子晶体的缺陷模式

关于bragg光纤的电磁波横模的计算，用其可以给加好的了解bragg的模式特性(on the transverse mode of the electromagnetic wave, can be used to increase their understanding of good characteristics of the model bragg)

基于MATLAB的批量提取图像的纹理特征，纹理特征提取的方法采用灰度-梯度共生矩阵法。(Extracted texture features based on MATLAB bulk, texture feature extraction method using gray level the- gradient co-occurrence matrix method.)

程序为将a律十三折线的PCM信号经量化后的信息编为0101二进制的编码。(Procedures will be a law broken line thirteen of the PCM signal after quantization information as binary code 0101.)

2D 粘弹性介质 全空间解析解，matlab。(2D viscoelastic medium analytical solution of the whole space, matlab.)

产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，分别设计三种高通，低通，带通滤波器对信号进行滤波处理，观察滤波后信号的频谱。(generating a continue time singal,which contains low,middle and high frequences,sampling it.analisize its spetrum.Then designing three kind filters are lowpass,highpass,bandpass filters and processing it.Observing its spetrum.)

this code is to diplay any wave file(heart sound) into PCG waveform

说明：  基于matlab的遗忘因子最小二乘递推算法辨识程序(Matlab-based forgetting factor RLS identification procedures)

已调试过，可产生需要的LDPC码，具体应用可以自己更改参数(the program has been runed succefully, can be used to produce LDPC code)

说明：  Matlab的一些应用程序例子，可以供大家参考下，谢谢大家的支持(Matlab some application examples, for your reference, thank you for the support )

微弱信号的检测和提取，用MATLAB语言实现，包括了小波法(Weak signal detection and extraction, using MATLAB language, including the wavelet method)
