提取心音信号的包络，matlab源代码

是Matlab图像处理的原程序代码，适合初学者使用。 (Matlab image processing is the original code, suitable for beginners.)

Yule-Walker

在加噪声的情况下，利用细菌觅食优化算法（BFA）辨识NARMAX模型(In the case of additive noise, the use of bacterial foraging algorithm (BFA) Identification NARMAX model)

阵列信号中常用的CBF、MVDR等波束形成算法的编写与基本性能分析(Array signal CBF, MVDR beamforming algorithm to write basic performance analysis)

OQAM-OFDM系统性能仿真,适合初学者，性能出图

背景处理的matlab处理程序。研究次课题的人可以参考(matlab)

这本matlab简单易懂，非常适合初学者，我就是看的这本教程才学会的、(This matlab straightforward, very suitable for beginners, I just look at this tutorial was learned,)

基于信息熵的迭代法求最佳阈值，并附参考论文及KSW熵法求阈值的程序。两个程序经实验测试通过无误。(Entropy-based iterative method for optimal threshold, together with reference papers and KSW entropy threshold method procedures. Two experimental test procedures correctly.)

Matlab preprocessor that replaces macros with their names

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)
