K-MeansDistance

图像均值和中值滤波,利用matlab软件编写，里面有代码说明，程序运行结果(Mean and median filtering image using matlab software development, which has the code description, the program runs results)

it is a camera for matlab

数值积分中matlab的实现，其中包括拉格朗日插值、辛普森插值等基本算法。(Numerical integration in matlab realization, including Lagrange interpolation, Simpson and other basic interpolation algorithm.)

利用ARMA、AR、MA模型，以及周期图等进行系统参数估计以及全相位FFT测相位(Using ARMA, AR, MA model, and the cycle map for system parameter estimation, and testing phases of all phase FFT)

先对语音信号进行采集、播放，分析其频谱，对该信号源添加噪声，再播放音频并分析频谱，然后分别通过IIR低通、带通滤波器和FIR低通、带通滤波器，分别播放音频和得到滤波后的频谱。(Firstly， voice signal acquisition, play, analyze its spectrum to add noise to the signal source, and then play the audio spectrum analysis, and then were by IIR low-pass, band-pass filter and FIR low-pass, band-pass filters, respectively, play audio and get the spectrum after filtering.)

说明：  基于非负矩阵分解（NMF）的人脸特征提取算法，NMF基本思想是找到一个线性子空间W，使的构成子空间的基本图像的像素点都是正值，而且人脸图像在子空间上的投影系数也是正数(Non-negative Matrix Factorization (NMF) of facial feature extraction algorithm, NMF basic idea is to find a linear sub-space W, so that the composition of sub-space of the basic image pixels are positive, and face image in the sub-space projection coefficient is positive)

产生射频噪声干扰信号，并画出他的波形和功率谱(RF signal generated noise, and draw his waveform and power spectrum)

此程序是一个动态的非线性的滤波器程序，对编程人员的能力要求比较高(This program is a dynamic non-linear filter program, the programmer the ability to require a relatively high)

It is a single phase half controlled inverter.
