Does u(u-1) indicate indexing u at index u-1 or does it indicate multiplying the scalar u by (the scalar u minus 1)?

syms u
n = 7;
A = [1,cumprod(u - (0:n))];
A =
[ 1, u, u*(u - 1), u*(u - 1)*(u - 2), u*(u - 1)*(u - 2)*(u - 3), u*(u - 1)*(u - 2)*(u - 3)*(u - 4), u*(u - 1)*(u - 2)*(u - 3)*(u - 4)*(u - 5), u*(u - 1)*(u - 2)*(u - 3)*(u - 4)*(u - 5)*(u - 6), u*(u - 1)*(u - 2)*(u - 3)*(u - 4)*(u - 5)*(u - 6)*(u - 7)]

u=input('Enter the value of u (more than 1): ');
n=input('Enter the numbers of Elements required: ');
a(1)=1;
for i=2:n
a(i)=a(i-1)*(u-i+2);
end
disp(a);

At some point you'll have to enter a value for u. Or do you plan on using the symbolic toolbox for further analysis?
