calc_phir0: Calculate root area ratio at reference diameter

In GJMeijer/FBMcw: Generic fibre bundle model for soil reinforcement by plant roots

Description

This function calculated the root area ratio at the reference diameter based on the total root area ratio, the diameter range and a power-law coefficient describing the root bundle.

Usage

calc_phir0(phirt, drmin, drmax, betaphi, dr0 = 1)

Arguments

phirt	Total root area ratio in bundle (numeric array)
drmin, drmax	minumum and maximum root diameter in bundle (numeric array)
betaphi	Power law coefficient for root diameter-root area ratio fit (numeric array)
dr0	Reference diameter (numeric scalar, default 1.0)

Value

numeric array with 'phir0' values

Examples

calc_phir0(0.01, 1, 5, -1)
