Hello,
I must calculate S in the range of n=1 to n=100 without a loop.
s=(1...100)(101-n)*cos(n/100)
Example= 100*cos(1/100) + 99*cos(2/100) ... + 1*cos(100/100)

n = 1:100 ;
s = sum(n.*cos(n/100))

If I understand the OP's question right, the solution might have to be:
n = 1:100;
s = sum(n(end:-1:1).*cos(n/100));
