display any single-band or triple-band image, by normalizing each band it so that the darkest pixel is black and the brightest is white

量子物理学中的常用算法与程序,对于学习量子计算与量子信息比较有帮助(Commonly used in quantum physics algorithms and procedures for the study of quantum computing and quantum information more helpful)

课程作业：利用贝叶斯进行数据集的分类，并评估分类结果(Using the Bayesian to classify the data set, and uating the classification results)

这是关于vmd变分模态分解的matlab代码，主要应用于信号的分解，数据的处理等。(This is the matlab code for VMD variational mode decomposition, which is mainly applied to signal decomposition, data processing and so on.)

一种基于多文档得图像合并技术，包括回归分析和概率统计，构成不同频率的调制信号，包含飞行器飞行中的姿态控制，如侧滑角，倾斜角，滚转角，俯仰角，利用matlab写成的窄带噪声发生，DC-DC部分采用定功率单环控制。

说明：  利用lingo求解最小连接问题 !如果数据量大的话，还是用书上的算法简单实用，见 数学建模导论 68页 (Minimum connection problem solving using lingo! If large volume of data, then he used the book simple and practical algorithm, see page 68 Introduction to mathematical modeling )

本文分析了语音数字信号的采集来源以及其预处理。通过实例，利用Matlab对语音信号进行时频变换与分析，同时构造一个固定频率的干扰信号，对两个信号进行合成，设计数字滤波器，实现对语音信号的F IR、IIR滤波处理，最后在时域和频域中对信号进行分析比较。(This paper analyzes the sources of voice digital signal acquisition and its pretreatment. By example, voice signals using Matlab time-frequency transform and analysis, and construct a fixed-frequency interference signals, the two signal synthesis, design digital filters to realize the speech signal F IR, IIR filtering, and finally time domain and frequency domain signal analysis and comparison.)
