Matlab Assignment.
Hello, I need help with a matlab assignment and I have no idea what to do.
The directions given are listed below:
Write a code to detrend the attached ECG signal and calculate the heart rate of it. [ecg.mat]
1) The sample frequency is 512Hz
2) You can use the following to read in the .mat file data to variable x.
A=load('ecg.mat');
x=A.ecgnl
Also heart rate = (60)/(measured frequency/512)
Below is a screenshot of the ecg.mat file. Unfortunately I could not attach the actual file.
