I have a question about how to write a code for this kind of summation. k is predetrmined and my problem is about how to set (n+k odd):
Thank you in advance for your help…

I am assuming that "" is scalar and hence taking it as "r", but that shouldn't matter for this question. Also please initialize r, k before attemting to run the code. Here is the sample code:
sum = 0;
for n = 0:k-1
if mod(k+n, 2) == 1
sum = sum + (2*n+1)*r;
end
end
Note: This is not an optimized code and you may write a more optimized implementation.
You simply have to go back to the definition of odd and even. An (integer) number is even if it is divisible by 2, odd otherwise. Divisible by 2 means that the remainder when divided by 2 is 0. That is easy to test, the function to get the remainder isrem (or you can usemod).
As with many things in matlab you do not need a loop, the functions work on vector / matrices
