this is the code to plot a signal loaded from physionet(MIT-BIH Arrhythmia database) but i get 2 signals in the same plot.what is the problem?
load ('100m.mat');
Ecg=(val-1042)/200;
fs=360;
ts=(0:length(Ecg)-1)/fs;
plot(ts,Ecg);

I think you may want to look at the file 100m.mat closely. It's likely that your variable Ecg (coming from val) has two entries instead of just one. How does one entry in 100m.mat look?
If the column 'val' has 2 columns, then use
Ecg = val(:,1)
(or 2 depending on what column is relevant)
Cheers.
