I need to solve the polynomial x^4+nx^3-1 for n=-1,0,1 (without using for loop)
What I did is:
n=(-1:1:1);
co_poly=[1 n 0 0 -1];
roots(co_poly)
but it just put the array n inside the coefficients array.

Harel - why don't you just iterate over each n and calculate the roots for that particular n? For example,
for n=-1:1:1
co_poly=[1 n 0 0 -1];
roots(co_poly)
end

Why can't you use for? Does the assignment prevent you from using that?
