The basic problem is that you are mixing character variables (with the single quotes ' ') with logical variables (without single quotes). E.g.,
result = true; <-- LOGICAL
if (n == 1)
result = 'false'; <-- CHARACTER
elseif (n == 2)
result = 'true'; <-- CHARACTER
else
for i=2:n-1,
if (mod(n,i)==0)
result = 'false'; <-- CHARACTER
end
end
end
if (result) <-- Intent of test is that variable is LOGICAL
result = 'true';
else
result = 'false';
end
So stick to one or the other. E.g., to use logical variables in the first part of your code:
if (n == 1)
result = false;
elseif (n == 2)
result = true;
else
for i=2:n-1,
if (mod(n,i)==0)
result = false;
end
end
end
