小波阈值去噪的源代码.不同的阈值函数可以修改阈值函数.从而实现功能.(wavelet thresholding source. Different threshold function can change the threshold function. Thus achieving functional.)

这是一个在matlab下模拟ask 和 bpsk调制和解调的代码(this is a file wirtten by Matlab, to explain the ASK and BPSK in a correctly way )

说明：  自适应中值滤波算法，可以用于图像去噪，比传统的中值滤波效果更好，运行时间更短(Adaptive median filter algorithm can be used for image denoising, than the traditional median filter is better, shorter running time)

时频分析方法提供了时间域与频率域的联合分布信息，清楚地描述了信号频率随时间变化的关系。(Time-frequency analysis method provides a time-domain and frequency domain, the joint distribution of information that clearly describes the signal frequency versus time relationships.)

用MOM方法数值计算二维导体柱散射问题，值得下载(MOM method using two-dimensional conducting numerical scattering problem, it is worth downloading)

利用差分fft 同步的算法 matlab编程实现(diff fft sync)

包含实例的MATLAB 克里金插值程序，注释清楚，方便移植(Contains examples of MATLAB kriging interpolation, comments clear, convenient transplantation)

说明：  最传统的拓扑优化程序，99行，使用优化准则算法（OC算法）(The most traditional topology optimization program, 99 lines, uses optimization criteria algorithm (OC algorithm))

借鉴了主成分分析算法（PCA），重要参数的提取，解耦，恢复原信号，双向PCS控制仿真，包含特征值与特征向量的提取、训练样本以及最后的识别，经典的灰度共生矩阵纹理计算方法。
