HELP!! I need to use a loop to make my cell array

I have a 40x1 cell array, "locations," where each element is a 270x33 matrix. My goal is a 1x1320 cell array, "master locations," where each element is a 270x1 column vector, which would be all of the individual columns from the elements of "locations." Essentially, I want a code that automates the following

master_location{1} = locations{1}(:,1) 

master_location{2} = locations{1}(:,2)
.
.
.
master_location{34} = locations{2}(:,1)
.
.
.
master_location{1320} = locations{40}(:,33)

Try this:

counter = 1;
for k = 1 : 40
    for col = 1 : 33
        master_location{counter} = locations{k}(:, col);
        counter = counter + 1;
    end
end

Why does it have to be a cell array rather than a simple, regular numerical array like a double?

I suppose it could be a double. I was wanting to make it a cell array for the purpose of organization. How could you make it a double?

Something like

master_location(counter, col) = locations{k}(:, col);

but you need to preallocate space for master_location before the loop. If you need more help, attach a .mat file with your data.

Or maybe what Ahmet gave will work. I like to have data to test with, so attach yours.

Huh, my answer to this question seems to have disappeared.

cat(2,master_location{:})

This should solve your specific problem. The output will be an array instead. If you really want a cell, use mat2cell afterwards.
