能量
我计算脉搏程序的谱能比，程序如下，运行结果显示 s1=; 有误，不知错在那里，望大家指导一二。=period(s);
N=N2-N1;
s=s(N1:N2);
t=wpdec(s',6,'coif3','shannon');
s60=wpcoef(t,); %0-1Hz
s61=wpcoef(t,); %1-2Hz
s51=wpcoef(t,);%2-4HZ
s64=wpcoef(t,); % 4-5Hz
s65=wpcoef(t,); %5-6Hz
s53=wpcoef(t,); % 6-8Hz
s54=wpcoef(t,); %8-10Hz
s55=wpcoef(t,);%10-12HZ
s43=wpcoef(t,); % 12-16Hz
s21=wpcoef(t,); %16-32Hz
s34=wpcoef(t,); % 32-40Hz
s10=wpcoef(t,); %0-32Hz
s11=wpcoef(t,); %32-64Hz
s1=; %0-10Hz
s3=; %10-40Hz
E1=s1*s1';
E3=s3*s3';
SER=E1/E3;
补充
=period(s); 提取信号的单周期波形
