Subscript indices must either be real positive integers or logicals

Question

iteration(it).NO=length_without_zero(CH); But i have this error in this line of my matlab code: Subscript indices must either be real positive integers or logicals.

In matlab, indexing is done from one. I'm guessing that iteration is a vector that you storing data in? If you type

iteration(0) = 10;

Then you will get that error message. My guess is that you come from another programming language where the value of 0 is used to refer to the first element of an array. Are you doing a loop to update the values in iteration? If so, you should do your loops with the it variable starting at 1. Like so;

for it = 1 : 10
    iteration(it) = it - 1;
end

thanks a lot , i resolved it i write it=1; instead of it=0; – sabkh May 08 '15 at 15:32 — sabkh, May 08 '15 at 15:32
