random numbers based on a "profile"

[Andybo]

Hi, I am trying to think of ways that i can take a block of numbers say 10 col, 10 row.
I intend to somehow 'profile' a completed table of numbers and then produce a replica set but slightly different following the same profile (i dont know how else to say it.) You can see there is a trend, how can i find the relationship or trend in the column and row and then randomize a similar data set with the same characteristics. so you could have a graph for each axis and then the new numbers will increase/decrease to that but also being random to within a few or specified amount (variance) asking a lot i know but i'll get there just hoping for some pointers. Thanks[TABLE="width: 500"]
