Wondering how to use the min/max function in an array?

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'
