These Functions were designed to eliminate baseline wondering and to detect the peaks of an ECG signal

Probably, there is an issue in your sampling frequency. To solve the issue, correct the following lines as adding the 'round' values

Q_th =round (20/360)*Sampling_frequency;
P_th_1st = round(40/360)*Sampling_frequency;
P_th_2nd = round(1/360)*Sampling_frequency;
S_th_1st = round(5/360)*Sampling_frequency;
S_th_2nd = round(60/360)*Sampling_frequency;

Possibly the issue will be gone. Thank you for using our function and We expect a rating from your point of view.
Than You

Hello, on the qrs detection the a value is not a positive integer or a logical value
