mpm_split: Convert matrix population model into U, F and C matrices

In Rage: Life History Metrics from Matrix Population Models

Convert matrix population model into U, F and C matrices

Description

Splits a matrix population model into three constituent matrices, U (growth and survival processes), F (sexual reproduction) and C (clonal reproduction). Warning! The functionality is very basic: it assumes that sexual reproduction is located in the top row of the matrix, and that everything else is growth or survival (i.e. the U matrix). Clonality is assumed to be non-existent.

Usage

mpm_split(matA)

Arguments

matA	A matrix population model (i.e., a square projection matrix).

Value

A list of three matrices: matU,matF and matC. matC will always contain only zeros.
