MapPhInfMCNMoments := proc(A, vA, lambda, R, B, mu, K, Pr, nodelist, lower, upper)

#
# this procedure returns a plot of the mean and variance of
# the number in system an at a list of nodes
# for a [Map_t/Ph_t/Infinity]^K network with R different arrival processes 
# 
# initial conditions for the queue are empty and idle
#
# this version is designed to work with Maple V release 5
#              
# last update 1/26/01
#
# Inputs:
# A = Markov chain transition matrix for the arrival process
#     [vector of matrices of dimension R]
# vA = number of absorbing states in Map representation
#     [vector of numbers of dimension R]
# lambda = arrival rate vector
#     [vector of vectors of dimension R]
# R = number of distinct Ph arrival processes
# B = Markov chain transition matrix for the service process
#     [vector of matrices of dimension K]
# mu = service rate vector
#     [vector of vectors of dimension K]
# Pr = Markov routing probabilities
# nodelist = list of nodes to be plotted
# lower, upper = range of plots
