If loclv is equal to index number , how can I keep the value in Data with index from loclv and change in other to 0 (Change only in column 2
clear
Data = readmatrix('Pure Brain Spectra.csv');
rows=length(Data)
cols=width(Data)
%for i = 2:cols
%hold on
Xlocs = Data(:,1);
Ylocs = Data(:,3);
select = [Xlocs Ylocs]
plot(Data(:,1),Data(:,3));
%for j=1:rows
value = findpeaks(Ylocs,Xlocs);
[pks,locsLiv] = findpeaks(Data(:,2));
%end
%hold off
%end
)

Hi,
From my understanding you are trying to replace values in second column in Data with "pks" at locsLiv as index and have rest indices to have a zero.
Adding the following lines of code should do the task
Data(:,2) = 0; % After line [pks,locsLiv] = findpeaks(Data(:,2));
Data(locsLiv,2) = pks ;
