I have a cell 41 * 41 dimension, and I would like to make the values over 0.5 equal to zeros in Matlab, and the rest of the values keep them without any changes. Is it possible to work directly on the cell, or do we need to convert it to a matrix first?

Any assistance, please?

My try

AAA = cell2mat( BBB );
for i = 1: length(AAA)
    for j = 1 : i
        if AAA(i,j) > 0.5
            AAA(i,i) = 0;
        else
            cc = AAA(i,j);
        end
    end
end

Since logical indexing is not supported for operands of type 'cell', you have to convert to matrix first. Use logical indexing on the matrix and convert back to cell. Assuming BBB is like BBB = num2cell(rand(41)), then

AAA = cell2mat(BBB);
AAA(AAA > 0.5) = 0;
BBB = num2cell(AAA)

You could use boolean indexing:

AAA[AAA > 0.5] = 0;
