Index in position 2 exceeds array bounds (must not exceed 14).

C(1,1)= 1; C(1,10) =-1; C(1,16) = 1

C(2,2) = 1; C(2,10) = 1; C(2,11) =-1;

C(3,3) = 1; C(3,11) = 1; C(3,12) = -1;

C(4,4) = 1; C(4,8) = 1; C(4,13) = -1;

C(5,5) = 1; C(5,4) = 1; C(5,14) = -1;

C(6,6) = 1; C(6,8) = 1; C(6,9) = 1; C(6,15) = 1;

C(7,7) = 1; C(7,15) = 1; C(7,16) = -1;

C(8,8) = 1; C(8,17) = -1;

C(9,9) = 1; C(9,17) = 1;

Odd! It works for me:

>> C(1,1)= 1; C(1,10) =-1; C(1,16) = 1;

C(2,2) = 1; C(2,10) = 1; C(2,11) =-1;

C(3,3) = 1; C(3,11) = 1; C(3,12) = -1;

C(4,4) = 1; C(4,8) = 1; C(4,13) = -1;

C(5,5) = 1; C(5,4) = 1; C(5,14) = -1;

C(6,6) = 1; C(6,8) = 1; C(6,9) = 1; C(6,15) = 1;

C(7,7) = 1; C(7,15) = 1; C(7,16) = -1;

C(8,8) = 1; C(8,17) = -1;

C(9,9) = 1; C(9,17) = 1;

>> C(9,17)

how is that possible? ... ( sorry I am not a pro, I am student and this happend for the first time )

[Alan Stevens]

I don't know! The only change I made was to put a semicolon after C(1,16), but I can't imagine that made a real difference!

[Marek Endrizal]

Thank you, I'll try to find solution ☺
