A =
2 3
4 5
>> trace(A)
ans =
7
>> trace A
ans =
65
Que: Why am I getting answer of trace A as 65??
(ASCI Value of A is 65)

That's because the functional form you are using when you enter
>>trace A
is executing
>>trace('A')
and in this case, it is nothing more than
>>sum('A')
Just like
>>help conv
is the same as
>>help('conv')
