I have a cell 41 * 41 dimension and I would like to make the values that over 0.5 zeros and the rest of the values keep them without any changes.

Any assistance, please?

If there's a single value in each cell, you could first convert to a matrix.

A = num2cell(rand(3))
A = 3×3 cell array
    {[0.2044]}    {[0.1296]}    {[0.9499]}
    {[0.3952]}    {[0.7477]}    {[0.1062]}
    {[0.9799]}    {[0.7201]}    {[0.6477]}
Amat = cell2mat(A);
Amat(Amat>.5) = 0;
A = num2cell(Amat)
A = 3×3 cell array
    {[0.2044]}    {[0.1296]}    {[     0]}
    {[0.3952]}    {[     0]}    {[0.1062]}
    {[     0]}    {[     0]}    {[     0]}
