Retinopathy detection

说明：  计算函数的极值的一种方法 只是其中一种 以后会陆续上新的(Calculation of the extremal function is just one of a method of the future will continue on a new)

混沌发展，历史和编码，混沌的研究方法及编码。(Chaotic development, history and coding, chaos research methods and coding.)

本文详细分析了MATLAB RTW下单机型模式（实时视窗目标）和双机型模式的 系统结构，确定了在MATLAB RTW下构建实时控制平台的方案。针对这两种模式， 本文提出对应驱动I/O板卡的方式，并将Simulink生成的仿真模型下载到实时内 核中运行，实现对控制系统的控制。(In this paper, a detailed analysis of MATLAB RTW under the stand-alone mode (real-time Windows Target) and dual-mode models of system structure, identified under the MATLAB RTW platform to build real-time control program. For these two models proposed in this paper corresponds to drive I/O board, and will generate Simulink simulation model downloaded to the real-time kernel to run, realize the control of the control system.)

一些基本的最优化方法的matlab程序，方便大家学习参考(Some basic optimization methods matlab procedures, facilitate learning reference )

进行C均值聚类，样本是男女身高体重数据，在程序中增加了很多注释说明部分，适合广大初学者。(Perform C-means clustering, the sample was male and female height and weight data, adds a lot of explanatory notes section in the program, for the majority of beginners.)

短时综合的滤波器组相加法的MATLAB程序实现(Short synthesis filter bank and adding MATLAB program to achieve)

说明：  这个程序和我上传的上一个程序有关，它可以将上个程序收集到的频谱数据进行拼接，从而在全频段进行展示，还能计算频谱上的信号频谱带宽和频点 主要参数 start_freq %扫频中心频率fc的起始频率， stop_freq %扫频中心频率fc的截止频率 rtlsdr_fs %每一次扫频的采样频率，改变他会影响每次扫频的带宽 nfrmhold %每次扫频的帧数 nfft %fft点数 overlap %扫频频谱的重叠率(dataspecrumcatch, catch the spectrum and It can also calculate the signal spectrum bandwidth and frequency point on the spectrum)
