Hello, I have an cell array with 1000 rows and inside of this rows I have a 3 word. I am taking the 2nd element of this rows and want to assign these values to another array. In other words array_temp(i,1) = array(i,2). I want to do it with for loop. How can I do it?

If array is a 1000-by-3 cell array, then you already know how to do it (here I'll use a 10-by-3 cell array):
% creating a 10-by-3 cell array of 'words':
array = mat2cell(char(randi(26,10,15)-1+'A'),ones(10,1),[5 5 5]);
disp(array);
n_rows = size(array,1);
array_temp = cell(n_rows,1);
for i = 1:n_rows
array_temp(i,1) = array(i,2);
end
disp(array_temp);
But a for loop is not necessary:
array_temp = array(:,2);
disp(array_temp);
On the other hand, if array is a 1000-by-1 cell array with each element being a 1-by-3 cell array (again, using size 10 instead of 1000 for demonstration), you can do it with a for loop like this:
% creating the cell array of cell arrays:
array = num2cell(array,2);
disp(array);
n_rows = size(array,1);
array_temp = cell(n_rows,1);
for i = 1:n_rows
array_temp(i,1) = array{i}(2);
end
disp(array_temp);
But again, an explicit for loop is not necessary:
array_temp = cellfun(@(x)x{2},array,'UniformOutput',false);
disp(array_temp);
If array is of some form besides one of these two, please post an example.
