How to do mirror padding to the matrix
I = [
1	6	3	3	4	5	1	2
2	5	7	2	2	2	6	2
4	4	6	8	3	5	3	8
5	3	3	4	5	2	2	7
6	5	2	2	7	6	2	4
7	1	4	2	3	5	3	3
2	4	2	4	7	3	3	2
1	2	4	5	6	2	3	1];
mirror_padding = [
1 1 2 4 5 6 2 3 1 1
2 1 6 3 3 4 5 1 2 1
2 2 5 7 2 2 2 6 2 2
8 4 4 6 8 3 5 3 8 4
7 5 3 3 4 5 2 2 7 5
4 6 5 2 2 7 6 2 4 6
