how to check values in a cell is smaller than a certain number?

hello i have a 1x12 cell which each of the matrix is No of days in a month(rows) with one column. and the data is average daily temperature. i need to check every values in the cell if they are smaller than 15.5 then do some calculation. how is would that be possible? regards

It's not very clear what is the structure of your cell array as I don't think you're using the correct terms. So can you show or attach a sample of your data? In particular, what's in each cell of your cell array, a matrix with several columns, the first of which is the number of day / month?

From what, I understand it's not the value of each element in the matrix you want to compare to 15.5, it's just the temperature (and not the number of days in the month).

here is the image. E is a cell of 1x12. does it make more sence? i need to check every value in cell E if they are smaller than 15.5. if they are smaller then do 15.5-thevalue if not 0.

[EDIT]

HDD = cell(size(E));
for jj = 1:numel(HDD)
    HDD{jj} = max(0,15.5 - E{jj});
end

thanks alot its working

Because it's a 1 x 12 cell you can address the i'th cell using E{i}

for i = 1:12
  smallvalues = E{i}(E{i} < 15.5);
  smallindices = find(E{i} < 15.5);
  % your computations ...

end

it is a 1x12 cell but the number of rows varies in each matrix is that gonna effect the code?

No, because cell arrays have been invented to handle different number of elements in each cell.
