MATLAB: X for y is

Question

my data is a table of 17439×3. With the lines being: time, displacement and force, respectively.

I Need all the corresponding values for time and displacement at the peak forces.

my code is

[pks] = findpeaks (-M2B{:,3},'MinPeakProminence',4);
pks = -pks;
idx = find(M2B{:,3} == pks(:,1);
loc = M2B{:,2}(idx);

this does however not work, if i insert pks (1,1) it does work but i dont get it to work for all values. Can anybody help?

Answer 1

[pks,idx] = findpeaks (-M2B{:,3},'MinPeakProminence',4);
pks = -pks;
peak_time=M2B{idx,1};
peak_displacement=M2B{idx,2};
