How to build a loop through every column and row of a cell

I have a 32 x 3 MATLAB cell and I want to loop through every one of the 96 cells to find the single largeset value contained in all of them? How might I go about doing that.

% first, I create a 32x3 cell array of random 10x10 matrices
C = arrayfun(@(x)randn(10),zeros(32,3),'uni',false)

C = 32×3 cell array
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}
    {10×10 double}    {10×10 double}    {10×10 double}

% now loop through all the cells and store 
% the largest value in each cell
C_max = zeros(size(C));
for ii = 1:numel(C)
    C_max(ii) = max(C{ii}(:));
end
C_max

C_max = 32×3

2.0129 2.2185 2.5962 1.6750 2.0335 2.5236 2.5415 2.8507 2.3550 3.0317 3.2665 2.4372 3.1738 2.4802 2.2340 2.2609 2.5011 3.6321 2.3977 1.9500 2.2795 2.4205 2.4711 2.3772 2.7915 1.6535 2.1038 2.8421 2.0512 2.6285

% finally, the single largest value
C_max = max(C_max(:))

C_max = 4.0026
