Hi Joseph,
I understand that you would like to index through 'data' using the indexing variable 'n'. The error you're encountering is due to the incorrect usage of indices in the code. In MATLAB, indices start from 1, not 0. Therefore, when you use n = 0:20, the indices in the subsequent if statement are out of bounds. You can refer to the documentation link below to know more about array indexing.
To fix this issue, you can modify the loop to start from 1 instead of 0. Additionally, you can remove the logical function calls in the if statement since they are unnecessary. You can modify the for loop as shown below:
for n = 1:20
if (data(n) > on_peak)
% Calculation
end
end
Hope this helps in resolving your issue!
