Let a and b be given by
a = [ 2 1 1 1
1 2 1 1
1 1 2 1
1 1 1 2
4 0 0 0 ] b = [ 2 1 1
1 2 1
1 1 2 ]then b can be created using a (b is wholly present in a). So output should be location of central element of b in a.
Here output is [3,3] else it should be [0,0].

in test case 3, b is not available in a. I might be wrong.. Please Check
Not logic to ask a scalar (if no location), an array (if 1), and a cell (if 2). And why not add the example (difficult) in the tests ?
@rifat : updated, thanks for info
Nice problem. Some solutions (using conv, filter2 etc.) doesn't check conditions properly. Adding a=2*ones(4); b=3*eye(3)+1; or a=0; b=0; or similar can improve the testsuite;
The solution in the example is [2 2;3 3].
