Hello I'm trying to execute the following code but in line 10 I get the error Index exceeds the number of array elements (16). How can I fix this?

Any help is much appreciated, Nicolás.

I=16;
J=8;
q=[17,4,12,13,16,15,14,11,10,9,8,7,6,5,3,2];

UC(j)=sum(r(L{j}));

r is not defined.

Thank you very much for the observation. I've already added it to the code.

Desde(j):Hasta(j)

In the above

Desde = [1 2 6] ;
Hasta = [0 4 23] ;

For j = 3

Desde(j):Hasta(j)
= 6:23 
=  6    7    8    9   10   11   12   13   14   15   16   17   18   19   20   21   22   23

You have used:

q(Desde(j):Hasta(j))

But size of q is 16, and your code tries to access more than present elements; you cannot find q([17 18 19 20 21 22 23]). So the error. You need to think on your code logic.
