How to make specific elements of a cell equal to zero?

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]}

newCell = cellfun(@(M) M.*(M<=0.5), YourCell, 'uniform', 0)

However this will fail in locations that contain infinite values.
