FFT_Analysis

MATLAB 和C语言进行混编的教程，很详细，具有较强的指导作用(MATLAB and C mixed language tutorial, very detailed, has a strong role in guiding)

说明：  this file contains the medical image processing. Here, I have to find the preprocessing methods. In this implementation i have to add the salt and pepper noise.

PDF制作 主要看画PDF相关功能。其他的无用哦。(PDF produced primarily PDF-related features painting. Oh, the other useless.)

正弦值查找表是用matlab代码写的，根据量化地址来查找实际地址的正弦值(Sine value lookup table is written in matlab code, according to quantify the address to find the actual address of the sine value)

心电检测中，是我自己编的毕设程序，有很多代码，包括心电处理的主程序，附程序，相关分析算法，谱分析算法以及各方法之间的对比。(ECG detection is my own series of complete set up procedures, there is a lot of code, including the main program of the ECG processing, the contrast between the attached procedures, correlation analysis algorithm, spectral analysis algorithm and method.)
