I would like to create an array of cos*n*x with n=0,1,2,3...N.

My code looks like this but it does not run.

L=51

N=(L-1)/2;

i=0;

for i=0:N

A=(:,i)=cos(i*pi);

end

Why do you need a loop?

L = 51;
N = (L-1)/2;
A = cos((0:N)*pi)

A = 1×26

1 -1 1 -1 1 -1 1 -1 1 -1 1 -1 1 -1 1 -1 1 -1 1 -1 1 -1 1 -1 1 -1

I didn't know I could do that.

Thank you very much.
