MATLAB: How can I convert matrix to cell

Question

A=[1 2 3;4 5 6;7 8 9]
A =
       1     2     3
       4     5     6
       7     8     9

How can I convert the above matrix into

A={'1' '2' '3';'4' '5' '6';'7' '8' '9'}
 =
    3×3 cell array
      '1'    '2'    '3'
      '4'    '5'    '6'
      '7'    '8'    '9'

Answer 1

 c = num2cell(A)

EDIT:

I just realized you want to convert them to char,

 c = arrayfun(@num2str, A, 'uni',0)
