KNNalgorithm

基于MATLAB的近似熵程序,主要用与生物信号的检测,主要用于生物医疗工程的信号处理方面(matlab program for calculating approximate entropy in biomedical signal processing especially.)

说明：  matlab主要函数指令表，按功能分类，非常方便好用的。(The main function matlab instruction sheet, according to the functions of classification, very easy-to-use.)

It is about the Randome distribution

高等數位訊號處理第九章作業 可以參考看看 裡面還有其他章作業(Advanced Discrete-Time Signal Processing )

简单易用的matlab FFT程序，零频在中间，另外还经常用的matlab绘图代码列了出来(Simple and easy-to-use program matlab FFT, zero frequency in the middle, is also often used matlab drawing code out)

利用MATLAB环境编写的程序集和，用来对波导杆上的超声波传播进行模拟。(PCdisp (Pochhammer-Chree dispersion) is a small toolbox of Matlab routines which simulate numerically the generation and propagation of ultrasonic waves in a cylindrical waveguide. PCdisp can: Trace the dispersion curves (wavenumber-frequency) for all propagating and evanescent modes in the waveguide Find and plot the distribution of displacements and stresses of a mode in the waveguide Use modal analysis to compute the amplitude of modes created in the waveguide by external excitations Simulate the dispersive propagation of waveforms along the waveguide.)

模式识别经典书籍的Matlab源代码，很适合从事神经网络，模式分类方面的研究人员(Pattern Recognition classic books Matlab source code, it is suitable for neural networks, pattern classification, researchers)

嵌套阵列DOA估计matlab例程，基于Nested Arrays A Novel Approach to Array Processing With Enhanced Degrees of Freedom。(Matlab simulation for DOA estimation with nested array.)

This matlab file plots the MUSIC spectrum for the antenna array to show the signals DOAs

说明：  自己编写的有关计算过零率以及基音周期的函数(I have written the zero crossing rate and the calculation of a function of pitch period)
