MATLAB: Averaging every n step column and m step row

averaging

Hi, Please help me to resolve the problem I have matrix 3D 8×84 below
X is time (January 2004 – January 2012)
Y is longitude
Z is Value
X = [01-2004 01-2004 01-2004 01-2004 01-2004 01-2004 01-2004 01-2004
    02-2004 02-2004 02-2004 02-2004 02-2004 02-2004 02-2004 02-2004
       :        :       :      :        :       :      :        :
    12-2011 12-2012 12-2012 12-2012 12-2012 12-2012 12-2012 12-2012]
Y = [40 50 60 70 80 90 100 110
     40 50 60 70 80 90 100 110
      :  :  :  :  :  :  :   : 
     40 50 60 70 80 90 100 110]
Z = [23 35 63 45 23 34 55 32
    14 23 34 43 18 26 44 22
     :  :  :  :  :  :  :  :
    21 43 65 22 86 43 66 33]
I want to averaging this matrix every month in every longitude. This would averaging Value at row 1,13,25,37,49,61,73, on longitude(1,1) So I have 3D matrix 8 x 12 (8 point longitude and 12 point monthly) Anyone can help?
