DNdog =

blnmynokta =
11

11
ksnkoor =
4

7
7
7
for i = 1:length(DNdog)
for j = 1:(length(blnmynokta))
if (DNdog(i) == ksnkoor(j))
A(i,j) = [0]
elseif (DNdog(i) == blnmynokta(j))
A(j,j) = [-1]
end
end
end
Formed matrix:
A =
-1 0 0
0 -1 0
0 0 -1
The matrix I want to form:
A=
0 0 0
0 0 0
0 0 0
-1 0 0
0 -1 0
0 0 -1
I do not understand where I made mistakes. Can you help me?

The index of A was wrong
clc
clear all
close all
DNdog =[7;7;7;11;11;11];
blnmynokta =[11;11;11]
ksnkoor =[4;4;4;7;7;7]
for i = 1:length(DNdog)
for j = 1:(length(blnmynokta))
if (DNdog(i) == ksnkoor(j))
A(i,j) = [0]
elseif (DNdog(i) == blnmynokta(j))
A(i,j) = [-1]
end
end
end
