While trying to execute the Pan Tompkins Code which was downloaded from the Mathworks, following error was encountered:
Error using pan_tompkin (line 118) Not enough input arguments.

You would get that error if you did not pass at least two arguments to the routine when you called it. You must pass at least the ecg data and the fs.

Sir, what are the steps to pass the arguments to routine in the above pan tompkins code?

pan_tompkin(ecg,fs,gr) is a function
ecg,fs,gr are arguments
To pass arguments mean to assign values to ecg, fs and gr.
ecg is ElectroCardioGram signal
fs is sampling frequency
gr is a flag to plot or not plot (set it 1 to have a plot or set it zero not to see any plots
Steps:
ecg = load('ECG_sample_noisy.mat');
fs= 256;
gr=1;
pan_tompkin(ecg,fs,gr) % To call function

Oh ok. Thanku so much, it did help. But again I am getting the error regarding arguments as below:
Error using plot Not enough input arguments.
Error in pan_tompkin (line 157) figure, ax(1)=subplot(3,2,[1 2]);plot(ecg);axis tight;title('Raw ECG Signal');

datacell = load('ECG_sample_noisy.mat');
fn = fieldnames(datacell);
ecg = datacell.(fn{1});
fs = 256;
gr = 1;
pan_tompkin(eg, fs, gr)
That is, you have to pass a particular variable from the .mat file. If you knew the name of the variable, such as by using
whos -file ECG_sample_noisy.mat
then you could work more directly. For example if the variable name was "Slithey_Toove' then you could use
datacell = load('ECG_sample_noisy.mat');
ecg = datacell.Slithey_Toove;
fs = 256;
gr = 1;
pan_tompkin(eg, fs, gr)

Sir, I have recently started working on Atrial Fibrillation(AF) related project. I have downloaded a few MIT_BIH AF signals from physionet.com. Could u just tell me as to how to pass these signals one by one in the Pan Tompkins Algorithm Code? Hope to get the help at the earliest!!
