DNdog =

blnmynokta =
11
for i = 1:length(DNdog)
for j = 1:(length(blnmynokta))
if (BNdog(i) == blnmynokta(j))
A(i,j) = [1];
elseif (DNdog(i) == blnmynokta(j))
A(i,j) = [-1];
end
end
end
A =
0
-1 % This matrix is formed.
The matrix that should occur is;

What exactly is your question?

A =
0 0 0
0 0 0
0 0 0
-1 0 0
0 -1 0
0 0 -1
I have to get this result. But I could not.

This is simple with toeplitz:
>> nC = 3;
>> nR = 6;
>> vC = zeros(1,nC);
>> vR = zeros(1,nR);
>> vR(end-nC+1) = -1;
>> toeplitz(vR,vC)
ans =
0 0 0
0 0 0
0 0 0
-1 0 0
0 -1 0
0 0 -1

nC = 6;
nR = 6;
If nC and nR take these values;
A =
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0
-1 0 0 1 0 0
0 -1 0 0 1 0
0 0 -1 0 0 1 %How can I get this value?

@Muhendisleksi: you can solve this yourself quite easily. One way would be to use zeros and toeplitz and concatenate the outputs on top of each other. When you actually read the documentation and try some examples then you will learn how to use MATLAB and you will learn how to solve problems yourself. Start by reading the docs for the two functions that I told you, and experimenting with them.
