How to get the matrix with maximum(or minimum) number of elements

Hi,

Suppose there are 3 matrixes A,B & C with sizes of [1 5],[1 8] and [1 9] respectively.

Is it possible to find the matrix with the maximum number of elements. Here it is C

This is the actual code I'm working on. Here I want to find that biggest matrix(y1 or y2). I know it can be done by typing length(y1) and length(y2) and choose the matrix with biggest one answer. But what I want to do is that I want to get it as an answer

load('chirp.mat');
y1 = transpose(y);
load('gong.mat');
y2 = transpose(y);

Thank you.

It is much easier to perform these kind of operations when all of the data are in one variable. So that is the first thing to do: lets put them all into one cell array (this is perhaps how they should have been saved anyway):

>> A = randi(9,1,5);
>> B = randi(9,1,8);
>> C = randi(9,1,9);
>> D = {A,B,C}; % put into a cell array

Now finding the array with the most elements is trivial:

>> N = cellfun(@numel,D)
N =
     5     8     9
>> [~,X] = max(N); % its index
>> D{X} % extract that array
ans =
     5     7     7     6     1     1     3     5     6

try

max(max(size(y1),size(y2)))

Sir,

Thank u very much for answer. But I'm afraid to say that it doesn't solve my problem. It returns the maximum value. What I want is to return what the biggest matrix is. In my code it should return 'y2'
