Heres problem 2 below for reference:

The ecg file is ecg1.mat for the code

My answer to problem 2

132-55=77

77/128=0.6015625

60/0.6015625=99.74bpm

Using the file in problem 2. Write a Matlab code that calculates the average heart rate (HR) in beats per minute (bmp) for this signal. Your code should work for any ECG. Your code should calculate the HR between every two consecutive peaks and then find the average HR for all peaks
