Subject: Get part of matrix

Hi!
I'm looking for a way to get part of matix: eg:
my matrix:
[10, 11, 12, 13, 14, 15, 16, 17, 18, 19]
[20, 21, 22, 23, 24, 25, 26, 27, 28, 29]
[30, 31, 32, 33, 34, 35, 36, 37, 38, 39]
[40, 41, 42, 43, 44, 45, 46, 47, 48, 49]
[50, 51, 52, 53, 54, 55, 56, 57, 58, 59]
[60, 61, 62, 63, 64, 65, 66, 67, 68, 69]
[70, 71, 72, 73, 74, 75, 76, 77, 78, 79]
[80, 81, 82, 83, 84, 85, 86, 87, 88, 89]
[90, 91, 92, 93, 94, 95, 96, 97, 98, 99]

How could i get part ( square ) of the matrix? If i choose the number
54, i would like to get the numbers [43,44,45,53,55,63,64,65], a 3x3
square.

I'm trying to understand the doc (
http://ruby-doc.org/stdlib-1.9.3/libdoc/matrix/rdoc/Matrix.html ).

There's a method to get this?

thanks,
Dieog
