1.基于上述峰值寻找程序的模块下，再加入一个判断条件，如果某一位的峰值所对应X轴的位数减去上一位峰值所对应X轴的位数不满足一个正常值的区间，则被判断为异常峰值，求该模块代码如何编写：
%%% 寻找峰值模块
for i=6:length(ecg)-6%正常峰值捕获
if(ecg_filtfilt(i)>=ecg_filtfilt(i+1)&&ecg_filtfilt(i)>=ecg_filtfilt(i-1)&&...
ecg_filtfilt(i)>=ecg_filtfilt(i+2)&&ecg_filtfilt(i)>=ecg_filtfilt(i-2)&&...
ecg_filtfilt(i)>=ecg_filtfilt(i+3)&&ecg_filtfilt(i)>=ecg_filtfilt(i-3)&&...
ecg_filtfilt(i)>=ecg_filtfilt(i+4)&&ecg_filtfilt(i)>=ecg_filtfilt(i-4)&&...
ecg_filtfilt(i)>=ecg_filtfilt(i+5)&&ecg_filtfilt(i)>=ecg_filtfilt(i-5)&&...
ecg_filtfilt(i)>threshold_soft) %门限条件
normal_peak = [normal_peak,ecg_filtfilt(i)];
normal_site = [normal_site,i];
%异常峰值捕获
elseif(ecg_filtfilt(i)>=ecg_filtfilt(i+1)&&ecg_filtfilt(i)>=ecg_filtfilt(i-1)&&...
ecg_filtfilt(i)>=ecg_filtfilt(i+2)&&ecg_filtfilt(i)>=ecg_filtfilt(i-2)&&...

ecg_filtfilt(i)<threshold_soft&& ecg_filtfilt(i)>12) %门限条件
abnormal_peak = [abnormal_peak,ecg_filtfilt(i)];
abnormal_site = [abnormal_site,i];
end
