Multiple variables in for loop
显示 更早的评论
Hello, I want to get each error value(E) for 3 a's. How can I do it ? (I don't know how to pre-allocate)
a=[11,51,101]
Toplam=0
x=pi/3
for (k=0:a)
x=(((-1)^k*(x))^((2*k)+1))/factorial((2*k)+1)
Toplam=Toplam+x
W=Toplam+x
E(a)=abs(W-0.86602540378444)
H(a)=E(a)/(0.866)
end

Something like this?
a=[11,51,101]
%preallocation
E=zeros(1,numel(a));
H=zeros(1,numel(a));
Toplam=0
x=pi/3
for (k=1:numel(a))
x=(((-1)^(k-1)*(x))^((2*(k-1))+1))/factorial((2*(k-1))+1)
Toplam=Toplam+x
W=Toplam+x
E(k)=abs(W-0.86602540378444)
H(k)=E(k)/(0.866)
end

NOTE: MATLAB arrays starts with index of 1. I think you meant to do the following:
a=[11,51,101];
Toplam=0;
x=pi/3;
H = zeros(3,1); E=zeros(3,1);
for i=1:length(a)
k=a(i);
x=(((-1)^k*(x))^((2*k)+1))/factorial((2*k)+1);
Toplam=Toplam+x;
W=Toplam+x;
E(i)=abs(W-0.86602540378444);
H(i)=E(i)/(0.866);
end
