i want to simulate ecg signal on matlab, we want that it counts 1 when R peaks are comes otherwise count 0 in one min. we want to design it using loop.plz tell me the programming.

hi,

I propose you use this function (Author : Floyd Harriott 2002) : http://www.physionet.org/physiotools/matlab/ECGwaveGen/ECGwaveGen.m

 fs = 5000;
 t = 0:1/fs:1;
 signal = rand(size(t)); %%%%test data
 fft_in = reshape(signal(1:256*floor(numel(signal)/256)),256,floor(numel(signal)/256));
 fft_out = fft(fft_in);

doc fft %the documentation example is very good

Good filtering example

ECG generator

Very simple example how to add noise to a wave:

t=0:0.1:10; %from 0 to 10 seconds, sampling 0.1 seconds
y=sin(t); %measured amplitude
n=0.1*rand(1,numel(t)); %noise to add
plot(x,y+n)
