门信号的波形及其频谱；付里叶变换的对称特性(Gate signal waveform and its spectrum Fourier transform symmetry properties)

可以实现动态绘制矩形、圆形、椭圆形等图样。matlab例程(Can dynamically draw the rectangle, round, oval and other patterns. matlab routines)

主成分分析法将图像分为低秩部分和稀疏部分(Principal Component Analysis (PCA) divides images into low rank and sparse parts)

说明：  利用冲击响应不变法和双线性不变法设计的巴特沃斯滤波器(Impulse response using the same method and design of the same bilinear Butterworth filter)

说明：  本文档中的源代码是利用谱减法对语音信号进行增强，再matlab中运行可达到预期的效果。(The source code in this document is to use spectral subtraction to enhance the speech signal, and then run matlab can achieve the desired results.)

this code is to do OCR using NN

变尺度随机共振代码，几年前用过的，很好用，喜欢的可以试试。(Variable scale stochastic resonance code, used a few years ago.)

MATLAB编写的基于决策树的ID3算法实现，模式识别，人脸识别。压缩包中包含两个源文件和测试图片，ID3源文件为主代码，fi为求熵函数。(MATLAB prepared based on the ID3 decision tree algorithm, pattern recognition, face recognition. Compressed package contains two source files and test images, ID3-based source code files, fi for the sake of entropy.)
