Hello Subroto. I have used a couple of steps to convert A into a vector of paired up pixels and stored it in A_paired.
>> A=[43 36 31 35 35 29 29 25
33 33 32 29 25 25 22 22
33 33 31 32 31 27 25 29
28 33 35 27 25 29 32 51
23 26 30 38 31 43 47 57
27 29 30 37 40 52 63 61
23 24 32 42 52 62 72 66
24 30 44 54 65 71 70 74 ];
>> A_transpose = A';
>> A_vector = A_transpose(:);
>> A_paired = reshape(A_vector, 2, length(A_vector) / 2)'
A_paired =
43 36
31 35
35 29
29 25
33 33
32 29
25 25
