HOW SHOULD DRAW THIS IN LOOP FORM? WHERE IS THE PROBLEM IN MY CODE?

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?

[Walter Roberson]

x is not defined by your code, so it will have whatever value is sitting around in memory.

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)

[Walter Roberson]

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

Answer 1

[HADIMARGO]

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)

Answer 2

[madhan ravi]

x=linspace(-5,5,10000);
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)

tnx for answering but the answer should be:
