Hello, Is there away to get nth power of polynomial without using symbolic calculation? For example f(x)=x^2+1 and I want g(x)=(x^2+1)^3 => x^6 + 3*x^4 + 3*x^2 + 1
so without symbolic variables => f=[2 1] => g=[1 0 3 3 0 1]
Thanks

Your ‘g’ is incorrect.
This works:
pn = [1 0 1]; % Polynomial
res = 1; % Result Variable
pwr = 3; % Power
for k1 = 1:pwr
res = conv(res, pn);
end
Result = res
