Arrays exercise Maximum and Minimum values

Hello,

I have this array

A=[1;0;0;4;5;6]

I want to get the maximum and minimum difference between the elements

MaxDiff= max(diff(A));
MinDiff= min(diff(A));

I would like to omit 'zero' in the calculations, so my output look like the two lines below. Which is not possible with the piece of code above

MaxDiff= 5
MinDiff= 1

Is there any way to do that without changing the size of my matrix A? it should be always 6 for future applications.

Thanks

>> B = nonzeros(A(:));
>> M = bsxfun(@minus,B,B.');
>> V = abs(M(~eye(numel(B))));
>> max(V)
ans = 5
>> min(V)
ans = 1
