getSrcDstIndices: Find indices of source and destination for each point-to-point flow
Description
This works only for routing matrices that include all
aggregate source and destination flows. It is often
easier to build these indices manually via string
processing or during the construction of the routing
matrix.
Usage
getSrcDstIndices(A)
Arguments
A
routing matrix of dimension m x k. This should
be the reduced-rank version including all aggregate
source and destination flows.
Value
list consisting of two component, src and dst, which are
integer vectors of length k containing the index (in y =
A x) of the source and destination flows that each
point-to-point flow is part of.
