Attempted to access d(1); index out of bounds because numel(d)=0.

c=6;
for i=1:c;
  d=find(sira(i,:)>0)
  l=length(d);
  TC=STC(1,d(1));
  t=0;
  T=0;
for  j=1:(l-1)
  t=CTC(d(j),d(j+1))
  T=T+t;

end;
T=T+TC;
  TT(1,i)=T;
end;
Topl=sum(TT);

error is at this line: TC=STC(1,d(1)); what is the reason ? and how can I solve this error. Could you help me ?

Have you tried using the debugger?

 dbstop if error

The answer should then become obvious.

After the line

d = find(sira(i,:)>0)

d can be empty, if no element of this line is greater than 0. We cannot suggest a change in the code, because we cannot know what you want to happen in this case. But you can detect it by:

if isempty(d)
