MATLAB: Finding size of a cell

Question

Hi everyone,

Let create a cell multi dimensinal cell A with the following code.

for k=1:4
    for i=1:k
        for j=1:2*k
            A{i,j,k}=num2str(100*k+10*i+j);
        end
    end
end
%------------------------------------------------------------------
%resault will be   
A(:,:,1) = 
      '111'    '112'    []    []    []    []    []    []
         []       []    []    []    []    []    []    []
         []       []    []    []    []    []    []    []
         []       []    []    []    []    []    []    []
A(:,:,2) = 
      '211'    '212'    '213'    '214'    []    []    []    []
      '221'    '222'    '223'    '224'    []    []    []    []
         []       []       []       []    []    []    []    []
         []       []       []       []    []    []    []    []
A(:,:,3) = 
      '311'    '312'    '313'    '314'    '315'    '316'    []    []
      '321'    '322'    '323'    '324'    '325'    '326'    []    []
      '331'    '332'    '333'    '334'    '335'    '336'    []    []
         []       []       []       []       []       []    []    []
A(:,:,4) = 
      '411'    '412'    '413'    '414'    '415'    '416'    '417'    '418'
      '421'    '422'    '423'    '424'    '425'    '426'    '427'    '428'
      '431'    '432'    '433'    '434'    '435'    '436'    '437'    '438'
      '441'    '442'    '443'    '444'    '445'    '446'    '447'    '448'
----------------------------------------------
% Now I want to find the size of A(:,:,2)  as 4 and 2. 
[r,c]=size(A(:,:,2))  will give a resault of 
[r,c]=size(A(:,:,2))
r =
       4
c =
       8

Do you know any function which gives the resault as 4 and 2?

Answer 1

Could you nest your cell array, using the line

>>  A{k}{i,j}=num2str(100*k+10*i+j);

Then use

>> size(A{2})
