primer: >> 3<5 ==>aus = 1

>> y = [6 3 2 1 6]
>> y>4 ==> [1 0 0 0 0 1]
>> z=[1 2 3 3 2 1]
>> y>z ==> [1 1 0 0 1]

>>all(y>4) ==> aus=0
>>all(y>0) ==> aus=1
>>any(y>6) ==> aus = 0

>> A==B
aus [1 1 1
     1 0 0
     1 0 0]

>>all(A==B)  ==> aus [1 0 0]
>>any(A==B) ==> aus = [1 1 1]
>>all(all(A==B)) aus = 0 <==> isequal(A,B)
find(y<5) ==> [1 3 4]
y(find(y<5)) ==> [1 2 3]
