fft变换 很好的例子，便于理解，请大家多支持(fft transform a good example of the ease of understanding, please support)

The Prediction Algorithm Based on Fuzzy Logic(Gradient_Descent approach)

This another matlab code for PCA-LDA

matlab绘制阵列正六边形。采用角度方法。(Draw a regular hexagon array matlab. Using the angle method.)

对于汉宁加窗的波束形成，阵列信号处理仿真源程序(Window for Han Ninja beamforming, array signal processing simulation source)

数字滤波器的matlab的例程，从基本的到高级例子，内有详细程序的说明及仿真结果(Digital filter matlab)

说明：  此程序是用matlab编写的FIR低通滤波器，为了区别于别人上传的都是调用了滤波器的现成函数filter，我自己用双重for循环编写了整个滤波过程，仿真已经通过……(This program is written in matlab lowpass FIR filter, in order to distinguish it from other people upload are ready-made function of the filter is called filter, for my own use a double for loop to prepare the entire filtering process, the simulation has passed ... ...)

Identifying overlapping period in time series. Required input: X = structure with in every cell (X{cell}) a measurement station. every cell has its first three columns as [year,month,day] Output: begin_date = is beginning date of overlapping periods end_date = end date of overlapping periods output = structure with overlapping periods filtered numcell = number of measurement stations

HHT是历史上首次对Fourier变换的基本信号和频率定义作的创造性的改进。他们不再认为组成信号的基本信号是正弦信号,而是一种称为固有模态函数的信号(HHT is the first time in the history of the Fourier transform basic definition signals and frequencies for creative change Progressive. They will no longer signal that the basic component signal is sinusoidal signal, but as an intrinsic mode function signals)
