Description

The proportion of each species (in each size class) that are considered mature. Matrue indisviduals contribute to SSB.

Usage

1
calc_maturity(nSize, nSpecies, mBound, scLinfMat, scLinf, parameterValues)

Arguments

nSize

Number of size class intervals species can grow through

nSpecies

Number of species in the model

mBound

Mid point of each size class interval

scLinfMat

A matrix (nSize x nSpecies) of binary values indicating which size classes each species occupies.

scLinf

A vector (length nSpecies) of size classes indicating the maximum size class a species can occupy. Based on L_inf (maximum length)

parameterValues

A Matrix of species specific parameters. See rochet_GB_parameterValues

Value

A matrix is returned

Maturity

A matrix (nSize x nSpecies) of Maturity proportions. Note: Maturity = 0 for size classes in which a species does not reach.
