MATLAB: How to apply column wise operation on each matrix in cell

if condition on a cell arrayMATLAB

I want to apply a condition of cell array allCells_array which contains matrices of 7×3 size.I want to check that if sum of each column of matrix is less than equal to 3 then do multiplication else go to next matrix in cell how to define this function and where to put END of IF in the given code?
for m=1:c2
    for n=1:numel(allCells_array)
        *here to put IF STATEMENT*
        movement=(all_comb_of_routes{m})*allCells_array{n};
        movement=movement>0;
        total_movement=sum((sum(movement,2))-1);
        count=count+1;
        total_all(count)=total_movement;
     end
end

Best Answer

Not quite sure what the loop over n is for, but from your words, it sounds like you want to do something like this:
for m = 1 : length(all_comb_of_routes)
  % Extract the 7-by-3 matrix from inside the cell
  thisCellContents = all_comb_of_routes{m}
  % Sum if vertically.
  columnSums = sum(thisCellContents, 1);
  % See if each column sums to less than 3
  % and multiply by some number.
  if all(columnSums < 3)
    % All 3 sums are less than 3.
    thisCellContents = thisCellContents * allCells_array{n};
    % Put new result back into the cell
    all_comb_of_routes{m} = thisCellContents;
  else
    % At least one of the columns sums to 3 or more.
    % Nothing to do, just skip to the end of the loop
    continue;
  end
end
