Equilibrium distribution from movement matrix

Source: R/model_int.R
calc_eqdist.Rd

Applies the seasonal movement matrices several times in order to obtain the equilibrium spatial distribution over the course of a year. Not used in the model but useful for reporting.

Usage

calc_eqdist(
  x,
  nm = dim(x)[1],
  nr = dim(x)[2],
  start = rep(1/nr, nr),
  m_start = 1L,
  nit = 20
)

Arguments

x

Movement array [m, r, r]. The second dimension corresponds to origin (sum to 1), and third dimension corresponds to destination

nm

Number of seasons

nr

Number of regions

start

The initial distribution. Vector of length nr

m_start

Integer, the season in which to apply the initial distribution and start the projection

nit

Integer, the number of times the movement matrix will be applied

Value

Matrix by season and region [m, r]
