I also never bothered to try speeding it up. Compiling to MEX is a direct solution. I'm not sure if it's possible to vectorize this algorithm in
I wrote a peak detection algorithm for heart rate only. See the second .m file. %% SpO2 R_RED = abs(Y1(pk_RED_i)/abs(Y1(1))); R_IR = abs(Y2(pk_IR_i)/abs(Y2(1))); R=R_RED/R_IR; SpO2(n) = 104 - 28*R end %% Take average value of heart rate and SpO2 HR=sum...

Load the ECG signal data. Filter the signal to remove noise using techniques like bandpass filtering or wavelet denoising. Normalize the signal to ensure consistent amplitude values. R Peak Detection (Q, R, S Points): Use peak detection algorithms like the Pan-Tompkins algorithm or findpeaks func...
algorithm is implemented in the Matlab® software environment as a user-defined function and several numerical experiments are conducted with real-world data for sake of verification and validation. The performance of the proposed method is compared with three other classic detection methods based on...
