Adding data to two matrices for indexing

I have 2 matrices Z and Y, both are a 10x1300 matrix and consists of random numbers, how do i add data to the left and right of each element and then use indexing to find Y for a certain value of Z

For example,

     Z [10 1300]  
     Y [10 1300]

One element in Z: 
Z(1,1)=10
z=Z(1,1)
Add data to left and right side, 
z-3,z-2,z-1,z,z+1,z+2,z+3 
Final result: 7,8,9,10,11,12,13

Similar for Y but with different data additions

One element in Y: 
Y(1,1)=20
y=Y(1,1)
Add data to left and right side, 
y+3,y+2,y+1,y,y+1,y+2,y+3 
Final result: 23,22,21,20,21,22,23

Use indexing to find Z=7 then find the respective element from Y would give Y= 23,

Y(find(Z==7))=23

Z=8,Y=22
Z=9,Y=21
Z=10,Y=20
Z=11,Y=21
Z=12,Y=22
Z=13,Z=23

I have no idea what it is you're asking. Your explanation is really unclear. Let's start with some smaller Y and Z, e.g. given:

Z = [10 7 9
     15 1 23];

and

Y = [20 1 13
     5  7  9];

what exact result do you want (and how do you get at it)?

result = [? ? ?
          ? ? ?];

Is it even a matrix the same size as Y and Z that you want as a result?

final Z 
[7 8 9 10 11 12 13 ¦ 4 5 6 7 8 9 10 ¦ 6   7  8  9 10 11 12 
 12 13 14 15 16 17 ¦-2 1 0 1 2 3  4 ¦ 20 21 22 23 24 25 26]

Final Y= [23 22 21 20 21 22 23¦ 4  3 2 1 2 3  4 ¦ 16 15 14 13 14 15 16
          8   7  6  5  6  7  8¦ 10 9 8 7 8 9 10 ¦ 12 11 10 9 10 11  12]

both are same sized, i need a way to add additional 6 elements into each and every element in the matrix

you can remove the ¦
