The logic is inconsistent. The following two conditions are both duplicated:

m = 0, n = -1

m = -1, n = -1

Answer 1

[KSSV]

m = 1 ; n = 1 ; 
if m == 1 && n == -1 
    h1 = 1 ; 
elseif m == 0 && n == -1
    h1 = 1 ;
elseif
    .
    .
    .
    .
end

Add your other cases.

[Deniz Bozdogan]

it always returns h1 as -1 since m=1 n=1

[KSSV]

Why? You don't want to change values of m and n?

Write it to a function with m, n as inputs and h1 as output.
