This error occurs when you try to extract more number of elements than present in the array.
EXample:
A = rand(1,10) ;
A(1) % no error
A(5) % no error
A(end) % no error
A(11) % error, as there are only 10 elements and you cannot extract 11th one.
Check your dimensions of the array and fix you loop indices.
