Getting an error "INDEX OUT OF BOUNDS" in my matlab program. Please help.

for i=1:3 fepsn(i)=i; end %%Loop for epsilon values for icounter=1:3 epsn=fepsn(icounter) end

%%Shape function for axial effect N1(epsn)=(-1/2)*epsn*(1-epsn) N2(epsn)=(1+epsn)*(1-epsn) N3(epsn)=(1/2)*epsn*(1+epsn)

%%First Derivatives of Shape Function N1=diff(N1(epsn),epsn) N2=diff(N2(epsn),epsn) N3=diff(N3(epsn),epsn)

%%%%Second Derivatives of Shape Function N11=diff(N1(epsn),epsn,2); Attempted to access N1(3); index out of bounds because numel(N1)=0.(ERROR HERE) N22=diff(N2(epsn),epsn,2); N33=diff(N3(epsn),epsn,2);

You accepted an answer for the same question a few minutes ago.

If the answer was not helpful, unaccept it and give the contributer a feedback.

Dont ask the same question again.

The problem was solved for that particular portion but not in this part. I rather suggest you to give solutions and not pin pointing and arguing with people Mr. Stephen

Usually duplicate questions will be closed. To get more help my suggestion is to unaccept the answer and tell the contributer who tried to help what went wrong by leaving a comment to the answer.
