If these are your inputs (see my comment):
C = cell(4, 4);
for iC = 1:4
C{iC} = rand(64, 64);
end
toAdd = [10, 20, 30, 40];
then a loop is working:
for iC = 1:numel(C)
C{iC} = C{iC} + toAdd(iC);
end
Or maybe you mean:
toAdd = 10 * (1:(64*64)); % Example data
for iC = 1:numel(C)
C{iC} = C{iC} + toAdd;
end
This can be achieve by arrayfun or cellfun also, but I consider a loop to be more clear and easy.

You can do it using arrayfun():
cellArray = ... % 64x64 array of cells
% define a 64x64 'addMatrix', its elememnts will be added to corrosponing cell of 'cellArray'
addMatrix = [10 20 30, ..... 640;
....;
....;
....]; % define a 64x64 matrix
result = arrayfun(@(x, y) x{:} + y, cellArray, addMatrix, 'UniformOutput', 0);
