How to find biggest element of the array?

I am aware max(A) will give me the biggest element, however it gives me another array with all the biggest elements.
Is there a way to do something like max(max(A))?

MAX works along a specific dimension (that you can specify using an extra arg). One way to find the overall max is to index A linearly and to pass this to MAX, e.g.:
max(A(:))

If A = [-1 0; -1000 -0.5], then px = max(A(:)) --> 0. The biggest element of the array is zero ?
We may perform as [px,i] = max(abs(A(:)); ax = A(i) --> -1000. The biggest element is then one thousand with minus sign !

Actually, the "biggest" element in your matrix A as defined by the original poster is 0, which is the absolute max. But I agree that "biggest" is not clear; however, the original poster clarifies the question by asking for an equivalent of max(max(A)).
