Description

Function to compute B and S matrices for moment equations of Vardi's method (1996). It's not particularly efficient, but it works.

Usage

1
vardi.iteration(A, yBar, lambda, B, S)

Arguments

A

routing matrix (m x k)

yBar

numeric vector of mean link loads (length m)

lambda

value of lambda from last iteration

B

B matrix computed by vardi.compute.BS

S

S matrix computed by vardi.compute.BS

Value

numeric vector of length k with updated lambda
