Caesar cryptic function problem.

I've written a code but im getting some error which Im not able to find out. Help me, please.

function coded = caesar(c,n)

X=c+n;

for ii=1:length(X)

if X(ii) > 126

X(ii)=X(ii)-95;

coded = char(X);

elseif X(ii) < 32

X(ii)= 95+ X(ii);

coded= char(X);

else

coded = char(X);

end

end

What are your inputs c and n?

Assuming c is a double array

function coded = caesar(c,n)
coded=char(mod(c-32+n,95)+32);
end
