Hey,
I have this cell with 12 different matrix. They are all of different size in length. How can I make all of them equal to 501 x 53 in size.

So what should happen to the larger matrices? Remove columns at random?

yes the other columns can be removed/deleted.

Which other columns? Pick them at random? The first ones? the last ones? Some other criteria?

for instances, the matrix in the first row has a size of 501 x 55, so to chnage its size to 501 x 53, column 54 and 55 should be deleated.

smallestwidth = min(cellfun('size', yourcellarray, 2)); %smallest width of all matrices in the cell array
newcellarray = cellfun(@(m) m(:, 1:smallestwidth), yourcellarray, 'UniformOutput', false); %crop all matrices inside the cell array to the smallest width
