Hello all, I am working on an ECG signal, i wish to know how to plot the ECG signal in respect of time scale. I am having 76801 samples with sampling rate 256Hz, i.e. 5 min of the signal. Please suggest a code if possible. Thanx in advance Arijit

You can use linspace to create a time vector for your EKG:
t = linspace(0, 76800, 76801)/256; % Time Vector (Intervals In Seconds)
Ts = mean(diff(t)); % Sampling Interval
Fs = 1/Ts; % Sampling Frequency (Check)

I just meant that if you take an ecg from say physionet and just load, eg. (load'100m.mat') it into matlab by default the array will be called "val", which i assume is short for values or something, but this is default for matlab.

It is always good MATLAB programming practice to load a .mat file to a variable. This creates a structure array that can then be addressed specifically to access the EKG record, the time vector, and other information. It also allows control over what gets loaded into the workspace as variables.

hello Mr star
Mr Star can i ask you please how to convert an ecg signal to image ??
i have a saved ecg file with(x:samples,y:amplitude,fs=2155 )
