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

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)

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)

I would like to make a small change in the answer.

Following is the correct code ::

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)

A=symsum(F,n,a(jj),a(jj));

SUM=SUM+A;

end

pretty(SUM)
