How about something like this:
x - matrix(1:100,10)
x.1 - array(-3, dim=c(12,12))
x.1[2:11, 2:11] - x
x.1
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11] [,12]
[1,] -3 -3 -3 -3 -3 -3 -3 -3 -3-3-3-3
[2,] -31 11 21 31 41 51 61 718191-3
[3,] -32 12 22 32 42 52 62 728292-3
[4,] -33 13 23 33 43 53 63 738393-3

[10,] -39 19 29 39 49 59 69 798999-3
[11,] -3 10 20 30 40 50 60 70 8090 100-3
[12,] -3 -3 -3 -3 -3 -3 -3 -3 -3-3-3-3
