hello everyone I wanted to know how to select a column for each iteration, for example I have a vector this vector contains a signal, then I divided this vector into a 24x64 matrix, what I need is that in each iteration grab these 24 and check if there is a peak .
any help will be greatly appreciated.
attached signal vector (PDP).
partbin = reshape (pdp,24,[]);
threshold = 0.0435;
for i= 1:length(partbin)
end

partbin = reshape (pdp,24,[]);
threshold = 0.0435;
for i= 1:size(partbin,2)
current_column = partbin(:,i);
% determine whether there's a peak in current_column,
% which is the i-th column of partbin
end
