How to loop through cell arrays

I have a 5x5 cell array, called H, that I am trying to loop through and do an equation on each cell. How would I do this?

I am using mat2cell to split a larger image,F2, into the 5x5 cell array.

H = mat2cell(F2, [40 40 40 40 40], [48 48 48 48 48])

To access the first part of the cell array I use H{1,1} but do not know how to automaticaly move onto H{1,2} until H{1,5} then move to H{2,1}.

I hope this makes sense.

Does the following push you in the correct direction?

for ii = 1:5
    for jj = 1:5
        fprintf('%0.f %0.f\n',ii,jj)
    end
end

S = size(H);
for rx = 1:S(1)
    for cx = 1:S(2)
         H{rx,cx}
    end
end

Hi,

First, you don't need to use cell array as your dimensions are all same. 40x48.

If you still want to work with cell array, you may try following:

h11=H{1,1}(:,:);

which converts the cell array inputs into matrix form. And then you do your equation on h11. General case,

for i=1: size(H,1) %scan rows
for j=1:size(H,2) %scan columns
hij=H{i,j}(:,:); %convert matrix form
hij_manipulated= equation (hij); %do the equation
H(i,j)={hij_manipulated}; %put it back to its original location in cell array
end

hello. can i use this equation for 444x200x400 double?
