I am getting error .....Array indices must be positive integers or logical values
in line of code 15 (Weigths(i)=(1+(i-1)/th)*(th-floor(th))/2+(1+(Tlag-i)/th)*(floor(th)+1-th)/2)
would appreciate help!!
Thanks
function [ Weigths ] = Weigfun(Tlag)
%WEIGFUN Summary of this function goes here
nmax=ceil(Tlag);
if nmax==1
Weigths=1;
else
Weigths=zeros(1,nmax);
th=Tlag/2;
nh=floor(th);
for i=1:nh
Weigths(i)=(i-.5)/th;
end
i=nh+1;
Weigths(i)=(1+(i-1)/th)*(th-floor(th))/2+(1+(Tlag-i)/th)*(floor(th)+1-th)/2;
for i=nh+2:floor(Tlag)
Weigths(i)=(Tlag-i+.5)/th;
end
if Tlag>floor(Tlag)
Weigths(floor(Tlag)+1)=(Tlag-floor(Tlag)).^2/(2*th);
end
end
Weigths=Weigths/sum(Weigths);

Suppose your input Tlag is negative...

Hi,
One plausible reason for you getting this error is that you might be calling the function with some negative value of ‘Tlag which results in a negative value of i’ variable (line 14). For example, if you run the code for Tlag = -5, then ‘i’ would be -2.
