My code is:
function i = Three_inputsFunction (x,y,z)
if x>y>z || y>x>z
x+y
elseif x<y<z || x<z<y
y+z
else
x+z
end
end
>> Three_inputsFunction (-18,-3,-6)
ans =
-21
Query : Why is the answer '-21' and not '-9'?

"Why is the answer '-21' and not '-9'?"
Because this code
x>y>z
is parsed from left to right as
(x>y)>z
which (because true==1 and false==0) is equivalent to either of these
1>z
0>z
You need this instead:
x>y && y>z
Also note that you do not define the function output i.
