a = input('What is a?','s');
b = input('What is b?','s');
c = input('What is c?','s');
d = input('What is d?','s');
Lengths = [ a b c d ];
S = min(Lengths)
L = max(Lengths)
PQ = sum(Lengths) - (S + L)
if S + L < PQ
Condition = 'Grashof'
elseif S + L == PQ
Condition = 'Special Grashof'
elseif S + L > PQ
Condition = 'Non-Grashof'
end
Whenever I input this, for a=7, b=11, c=8, and d=9, it gives me that S=49 and L=57. I want S=7 and L=11

You are using the 's' option for input(). That means that you want characters back instead of numbers. 49 corresponds to the character '7'
