How to add rows of a cell

I have a cell of size 9x3. How can I add all the rows of this cell, and get 3(number of columns) separate arrays out of this cell. and allocating each array a title, like (xx, yy , zz).

See this: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F

then try this:

% Add columns
xx = sum([ca{:, 1}])
yy = sum([ca{:, 2}])
zz = sum([ca{:, 3}])
