I am trying to calculate a sum series. Series upper limit chance btw 4:2:16 and i want to keep for loop iterations in an array cause i will make a plot N vs Stot.

syms j

for N=4:2:16

S(i)=(symsum(cos((20*pi*j)/(N+1)),j,0,N))

Stot=(2*pi/(N+1))*S;

double(Stot)

end

在 MATLAB Online 中打开

use

slot(i)=(2*pi/(N+1))*S;

Example:

for i=1:10;
    k(i)=2+i;
end

Command Window

>> k
k =
       3     4     5     6     7     8     9    10    11    12

i am using S1 formula. İ want to chance N like N=4:2:16 it is 10 in this case but at the same time i want to keep all of summation results in an array cause i will make a plot from them.
