利用FFT進行心電訊號除噪並截取R波特徵點

                           MatLab ECG Processing
                               Demo for Win32


I. How to use:
   1. Copy files 

         ecgdemo.m       ,
         ecgdemomex.dll  ,
         ecgdemolib.dll  ,
         ecgdemodata1.mat,
         ecgdemodata2.mat

      (all the files except this "readme.txt" file) into MatLab's work
      directory.
   2. Start up MatLab.
   3. Type in 

         ecgdemo

      and press "Enter".
   4. You will get two figures everyone of which has 6 plots:
         a. The first plot shows original ECG data;
         b. The second plot contains corrected ECG - the low-frequency
            component was removed;
         c. The third plot shows the data after 1-st filtering pass, the
            filter window is of default size so the result is not "clear";
         d. The fourth plot shows detected peaks - on this stage some peaks
            can be skipped;
         e. Here we analyse the result of peak detection and optimize the
            filter window size. So the fifth plot contains the result of
            2-d filtering pass.
         f. Sixth plot shows the final result.

II. Package content:
   1. ecgdemo.m        - MatLab demo script;
   2. ecgdemomex.dll   - MatLab "mex"-interface for ecgdemolib.dll library;
   3. ecgdemolib.dll   - processing core, real production module modified
                         to give out intermediate results;
   4. ecgdemodata1.mat - 1-st data sample;
   5. ecgdemodata2.mat - 2-d data sample;
   6. readme.txt       - this file.
