Generate the Pre (|v| by |u|) matrix for the SPN. This gives the edges from P to T (input arcs) in the bipartite network.

spn_Pre(spn_P, spn_T)

Arguments

spn_P

set of places (P) (see details)

spn_T

set of transitions (T) (see details)

Value

a matrix of type dgCMatrix-class

Details

The places (spn_P) object is generated from one of the following: spn_P_lifecycle_node, spn_P_lifecycle_network, spn_P_epiSIS_node, spn_P_epiSIS_network, spn_P_epiSEIR_node, or spn_P_epiSEIR_network.

The set of transitions (spn_T) is generated from one of the following: spn_T_lifecycle_node, spn_T_lifecycle_network, spn_T_epiSIS_node, spn_T_epiSIS_network, spn_T_epiSEIR_node, spn_T_epiSEIR_network.
