Principal Component Analysis code

基于DCT离散余弦变换的JPEG数字图像压缩MATLAB程序。(Discrete cosine transform DCT-based JPEG image compression MATLAB.)

说明：  测试nsga2的优化性能,包含zdt系列、sch系列，支持三个目标下的约束求解(NSGA-II TEST,including zdt series,sch series and is okay for a 3-dimensional minimization problem.)

crosscorrelation in matlab

matlab源程序： 用Fisher两类判别法对样本进行分类 对样本进行主成分分析 用最短距离算法的系统聚类对样本进行聚类 用二次完全式回归法估计一个因变量与两个自变量之间的关系 (matlab source: The Fisher discriminant method, two types of samples to classify the samples by principal component analysis system using the shortest distance clustering algorithm for clustering of samples with the quadratic regression method to estimate a fully dependent variable and two independent variables of the the relationship between the)

：通过对数字信号处理课程的改革，增加了DSP系统的设计和开发的课程，拓宽高校电子工程类专业学生在DSP方面的知识，进一步培 养他们的动手能力和创新能力。该课程实验中需要使用到初学者开发套件——美国1rI公司的TMS320C5402DSK。本文将重点介绍该DSK板的硬件体系，并且简要介绍了与该硬件体系相对应的CCS2．0限制版集成开发环境，并进一步讨论了在此套件基础上所开设的一系列DSP实验内容。(The course of design and development of DSP system is appended during the teaching reform of Digital Signal Processing．This course can expand the E．E．undergraduates’knowledge of digital signal processor．Therefor．their practical ability and innovation idea are enhanced．TS320C5402 developer start kit provided by Texas Instruments Company iS introduced in this paper．Its hardware structure and soft— ware development environment(Co de Co mposer Studio 2．0 limited)are discussed in details．The content of experiments based on this DSK iS presented furthermore)

基于GUI数学建模，当需要进行绘图时，可以进行界面设计，简单绘图，还有进行最优化公式的计算。(GUI Mathematical modeling)

这是一个纯MATLAB编写的俄罗斯方块的游戏。游戏非常的简单，只需上下左右四个键就能操作。算法较为精炼，值得参考。(This is a matlab code about RussionBlock. It s easy and useful. It worth your time on it.)

我上传一个用Matlab画的光学双稳特性曲线程序，欢迎大家提出宝贵意见(I upload a painting using Matlab optical bistable characteristic curve procedures, welcome you to give valuable advice)
