Is it possible to do this without a loop

Is it possible to create a vector like this without a loop?

I have only managed v2 with a loop that goes like this:

for k=1:100

v2(k)=cos(k*pi/8)

end

Try this:

n = 1 : 100
v2 = cos(n * pi / 8)
n = 1 : 30
v3 = n .* exp(n/10)

Answer 2

% The cos function operates element-wise on arrays 
v2 = cos((1:100)*pi/8);
