How to find the size of a cell array

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?

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

The problem is that there are multiple datatypes (??? All contents of the input cell array must be of the same data type.) All I want to know is the size of this mixed cell array?

Brian, do you have nested cell arrays?

Shouldn't be nested, if it's the raw output from xlsread, but perhaps there are multiple of these are being read into a cell?
Brian, can you show the code that's leading to the error message you've copied above (assuming that's what "??? All contents..." is), and/or explain more what you're trying to get? The raw output from xlsread is a cell array where each cell corresponds to an Excel cell, so size(raw) should give the number of rows and columns, as Sean says.

One more doubt pls..
I have a cell array that may be empty,having one element or more than one element. how can i make decision accorind to size of cell array ?? ie. size(s) = 0 1 or size(s) = 1 1 or size(s) = 3 1 . I only need the information that how many rows are there Thnks in advance
@Labeeb, this really should be a new question. The answer is to use isempty.
doc isempty
