Growing a Cell Array

I have created a cell array of size {1,1} but what if i want to add other matrices in the array? Do i have to preallocate it or will it automatically grow as I add contents in the cell array?

Hi Victor,

it will automatically grow:

x = {1}
x = 
  [1]

x{3} = 'Hello'
x = 
  [1]    []    'Hello'

Nevertheless, if the array will become large and you know the size before, preallocation, e.g. in this case

x = cell(1,3);

saves time.
