I have a cell array (raw from xlsread) that contains multiple data types. Is there a way to measure the size (length and width) of this cell array or convert it to a matrix so I can use the size function?

在 MATLAB Online 中打开

A = cell(20,11);
size(A)
ans =
  20    11

works for me... ? Or do you want the size of the contents of each cell?

cellsz = cellfun(@size,A,'uni',false);

Addendum per comment:

I still am not getting what you want.

clear A
>> A{1} = single(ones(4));
>> A{2} = uint8(toeplitz(1:10));
>> A{3} = 'Hello World'
A = 
  [4x4 single]    [10x10 uint8]    'Hello World'
>> size(A)
ans =
   1     3
>> cellsz = cellfun(@size,A,'uni',false);
>> cellsz{:}
ans =
   4     4
ans =
  10    10
ans =
   1    11
