Need Help Indexing. I have a 1x12 cell array with each cell containing a 120x2 double. I need to use a for loop to index all the values in every of row in the second column of the 120x2 double and store them in their own 1x12 matrix.

Cool = Matrix(:,2);

[row,col] = size(Cool);

N = 1;

M = 1;

for N = 1:1:col

for M = 1:1:row

Cool_Temp{M} = Cool{M}(:,2);

end

end

Do you necessarily do with a for loop? If not, you don't need one.

% an example
tst = cell([1, 12]);
tst(:) = {randn(120, 2)};

% extract the second column of each cell element and store them in another cell
res = cellfun(@(x) x(:, 2), tst, 'UniformOutput', 0);
>> res

res =

  1×12 cell array

  Columns 1 through 6

    {120×1 double}    {120×1 double}    {120×1 double}    {120×1 double}    {120×1 double}    {120×1 double}

  Columns 7 through 12

    {120×1 double}    {120×1 double}    {120×1 double}    {120×1 double}    {120×1 double}    {120×1 double}
