MATLAB: Summation for series (symsum function), only want odd numbers

Question

Hello All,

What I'm having trouble with is that I only want odd values n eg 1 3 5 7 9 inputted.

Is there a way I can go about this?

Code

Sums n x
Symsum(0.5+(2/pi).*((1/n).*sin(2.*pi.*n.*x)),n,1,9)

Answer 1

That is Square function ,the task needs skills, you can try loop , it is possible to work :

 syms x n 
SUM=0;
a=1:2:9;
F=0.5+(2/pi).*((1/n).*sin(2.*pi.*n.*x));
 for jj=1:length(a)-1
    A=symsum(F,n,a(jj),a(jj+1));
    SUM=SUM+A;
end
pretty(SUM)
