how to generate path matrix?

n=3;ri=0.9;lamda=0.7;

config = dec2bin(0:2.^L-1)-'0';

12 13 23

0 0 0

0 0 1 .r2

0 1 0

0 1 1 r1. .r3

1 0 0

1 0 1

1 1 0

1 1 1

consider 3 nodes (i.e., 1,2,3),this is fixed network. 1 is source node,3 is destination node and 2 is intermediate node. the shortest path is 1 to 3, because fixed network 1 is source and 3 is destination.

but i need this

12 13 23 path

0 0 0 0.00

0 0 1 0.00 % there is no connection with source node (that means 1 to 3 there is no path)

0 1 0 r1r3

0 1 1 r1r3

1 0 0 0.00 % there is no connection with destination node(that means 1 to 3 not connected)

1 0 1 r1r2r3

1 1 0 r1r3

1 1 1 r1r3

please to generate above table. please help me.
