Generate a matrix of straying proportions within a metapopulation

Description

Generate a matrix of straying proportions within a metapopulation. Based on Eq. 2 in Cooper and Mangel (1999).

Usage

generate_straying_matrix(n_pop, stray_fraction, stray_decay_rate)

Arguments

n_pop	Number of subpopulations.
stray_fraction	Fraction of individuals that stray from a given subpopulation.
stray_decay_rate	Exponential rate that straying decays with distance between subpopulations.

Examples

x <- generate_straying_matrix(10, 0.01, 0.3)
