Write a matlab function, gseq(n), that will calculate G(n).
I have tried and tried to do this but keep getting it wrong, and dont know exactly where i am going wrong. This is what i have tried, could anyone please tell me where i have gone wrong? thankyoU!!
function g = gseq(n)
%G(n) Calculates nth gseq number.
if n < 0
error('n is less than zero');
end
if n < 2
f = n;
n = 2
f = n-1;
else
%tmp is a temporary vecoter used to store the gseq numbers.
tmp(1) = 0;
tmp(2) = 1;
tmp(3) = 1;
for inum = 3:n
tmp(inum+1) = 3*tmp(inum) - tmp(inum-2) - tmp(inum-2);
end
g = tmp(n+1);
end
