my code:
s=0;
for n=1:0.01:10
s=s+(-1^n+1*sin(n*pi*x));
end
f=(2/pi)*s;
plot(x,f)
Where is wrong in my code?

i defined x but the result is not correct yet. and the amount of f are so big, why?
my code:
x=-5:1:5;
s=0;
for n=1:0.01:10
s=s+(-1^n+1*sin(n*pi*x));
end
f=(2/pi)*s;
plot(x,f)

You are defining x to have only 11 points, to exist only at the integers. Your required plot is clearly defined much denser than that.

i could do this but it is not still correct completely

finally i could write the correct answer! hahaha
tnx guys for pushing me lonely!
x=linspace(-5,5,1000);
s=0;
for n=1:1:10000
p=((-1)^(n+1)*sin(n*pi*x))/n;
s=s+p;
end
f=(2/pi)*s;
plot(x,f)
