let

 a = [1,2,3;4,5,6;7,8,9]
 b = 1
 c = b-a

if an element of 'a' becomes 0 after c operation it should be fixed i.e. on first operation

c = [0,1,2;3,4,5;6,7,8]

now output should be , 1 of first output should be fixed and

 c = [1,2,3;4,5,6;7,8,9]
 c = [1,1,2;3,4,5;6,7,8]
 c = [1,1,1;2,3,4;5,6,7]
 ............... and so on

Note that you can generate every output of your example in one command, where each row corresponds to one output:

>> toeplitz(ones(1,9),1:9)
ans =
 2   3   4   5   6   7   8   9
 1   2   3   4   5   6   7   8
 1   1   2   3   4   5   6   7
 1   1   1   2   3   4   5   6
 1   1   1   1   2   3   4   5
 1   1   1   1   1   2   3   4
 1   1   1   1   1   1   2   3
 1   1   1   1   1   1   1   2
 1   1   1   1   1   1   1   1
