How to select columns from data matrix using for loop?

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
