Calculating BPM - from PPG signal

Hi everyone,
I've been able to create a script that reads heart rate - displaying the value in real time on a graph.
Now i need to calculate the number of peaks in the graph and work out the BPM
Any simple script solution?
Any help will be most appreciated! Thanks!

Sir/Madam, could you share source code for ppg extraction from face video that is real time and along with I want to display a graph for that.

Check out the findpeaks command. Alternatively (if you do not have access to the Signal Processing Toolbox) you could do a Fourier Transform and look at the dominant frequency components.

Check out the code I write in here.

The heart rate estimation is done both by FFT or Peak detection.
