Plotting summation using for loop
显示 更早的评论
How would I plot values of i for 1,2,3,4,5 individually on the same graph?
x = -pi:0.1:pi;
ye = cos(x);
n = length(x);
summe = 0.0;
for i = 1:n
summe = summe +((-1).^(i)).*((x.^(2.*i))./(factorial(2.*i)));
end
hold on
plot (x, summe);
plot (cos(x), ye)

In previous question, as I told you, if you want your n vector as n=1:5, then you have to set your x vector as
x=-pi:pi/2:pi
and
n=1:length(x)
but it will be not wise to do this since when you plot, the figure will be a triangular shape. Therefore, you have to sample as many points as you can,
x = -pi:0.1:pi
is a wise choice.

x = -pi:pi/2:pi;
xx= -pi:0.1:pi;
ye = cos(xx);
n = length(x);
i=1:n;
summe=0;
for i = 1:n
summe = summe + ((-1).^i).*((x.^(2*i))./(factorial(2.*i)));
end
plot (x, summe);
hold on;grid on
plot(xx,ye)
