graphs (expressed as
lists of connected nodes)
1  convertGraph(Graph)

Graph 
array of dimension

An array of dimension p x p x NG
, or,
when NG
is equal to 1, a matrix
of dimension p x p
.
The entry [,,iG]
is a symmetric matrix, with diagonal equal to
zero. The entry [a,b,iG]
is equal to 1 if a
is connected to b
,
0 otherwise.
This function is useful to generate the entry
MyFamily
of the function selectMyFam
.
Actually, the list of adjacency matrices MyFamily
can be generated from lists of connected nodes with
convertGraph
.
