FFT_DEMO_with_MATLAB

一维云发生器，matlab编写，比较好用(the yun generator which is good)

说明：  MATLAB主成分分析，改变变量后可以用于因子变量分析，生物学上的(MATLAB component analysis, change the variables can be used to factor multivariate analysis, biological)

产生64QAM基带通信系统发射机：基带成型滤波采用3种方式（1）采用每个符号调制一个成型滤波函数，然后将各个函数进行时域叠加的方法； （2）采用信号与低通滤波器响应函数卷积的方法；（3） matlab自带的升余弦函数(Produce 64QAM baseband communication system transmitter: baseband shaping filter uses three ways (1) the use of a molding each symbol modulation filter function, and then each time domain overlay function (2) the use of signals and low-pass filter response function convolution method (3) matlab comes with a raised cosine function)

K-NN k-Nearest Neighbor classification algorithm

说明：  Particle swarm optimization

雷达系统分析与设计使用MATLAB第二版 Pdf(Radar Systems Analysis and Design Using MATLAB Second Edition Pdf)

用MATLAB内含的随机数生成器生成所需的随机量，是进行概率模拟编程的参考工具(Included with the MATLAB random number generator to generate the required random quantity is the probability of a reference tool for simulation programming)

Descriptor for simple shapes (e.g letters). Computes the descriptor twice in order to describe horizontally and vertically with the same accuracy. Input: image (2-D, binary or gray) depth of recursion (default 7), plotFlag(if on - plot Illustration) Output: vec - descriptor: Division locations, values around zero. Of length 2*(2^depth - 2) (levels: the depth of the division locations.)

说明：  基于无速度传感器感应电机的自适应识别自制程序(Self-made program of self-adaptive recognition based on speed sensorless induction motor)

说明：  该程序利用小波多尺度分解，提取近似系数和细节系数重构原图像(It uses wavelet decomposition to extract approximate coefficients and detail coefficients of the original image reconstruction)
