create_matrix_parameter: Make parameter matrix

In ATNr: Run Allometric Trophic Networks Models

Make parameter matrix

Description

Make parameter matrix

Usage

create_matrix_parameter(BM, b0, bprey, bpred, E, T.K, T0, k)

Arguments

BM	float vector, body mass of species.
b0	const
bprey	const
bpred	const
E	const
T.K	Celsius to Kelvin conversion
T0	Default temperature in Kelvin
k	Boltzmann constant

Details

Make a parameter matrix that depends on both predators and prey and that is used to define attack rates and handling times based on the general allometric equation:

p_{i,j} = b_0 * BM_i^{bprey} * BM_j^{bpred} * exp(-E * (T0-T.K) / (k * T.K * T0))

Value

A matrix filled with estimated values for a model parameter that depends on prey and predator body masses (see details)
