how to from a neural network to a set of matrix

If we have 8 activities like A, B, C, D, E, F, G, H

I need to from a network

where each activity has a values like this

A 10 20

B 3 4

C 4 7

D 1 5

E 5 6

F 6 8

G 11 7

H 3 8

The network has to be fromed like this into diffrent sets with their data in a matrix

SET1 SET 2 SET 3 SET 4

A A A A

B B B B

C C D D

E F G F

H H H H

is it possible to get this type of code to from a set from the network diagram

thanks
