Compare numel of multiple variables

How can I compare the sizes of multiple variables easyly?

%%
a = [1 2 3 4] ;
b = [1 2 3 4] ;
c = [1 2 3 4] ;

all_numel_equal = numel(a) == numel(b) == numel(c)   % Evaluates to false, because 4 == 4 == 4
                                                     % evaluates to true == 4 


% first not so elegant possiblitly:
all_numel_equal = (numel(a) == numel(b)) &&...
                  (numel(a) == numel(c)) 


% second ugly possiblity:
try
    [a(:) b(:) c(:)] ;
    all_numel_equal = true 
catch
    all_numel_equal = false 
end

Answer 1

[Matt J]

a = [1 2 3] ;
b = [1 2 3 4] ;
c = [1 2 3 4] ;

isequal(numel(a),numel(b),numel(c))

ans = logical
   0

Answer 2

[Matt J]

a = [1 2 3] ;
b = [1 2 3 4] ;
c = [1 2 3 4] ;


L=cellfun(@numel,{a,b,c});

all_numel_equal = all(L==L(1))

all_numel_equal = logical
   0

~any(diff(cellfun(@numel,{a,b,c})))
