The proportion of each species (in each size class) that are considered mature. Matrue indisviduals contribute to SSB.
calc_maturity(nSize, nSpecies, mBound, scLinfMat, scLinf, parameterValues)Number of size class intervals species can grow through
Number of species in the model
Mid point of each size class interval
A matrix (nSize x nSpecies) of binary values indicating which size classes each species occupies.
A vector (length nSpecies) of size classes indicating the maximum size class a species can occupy. Based on L_inf (maximum length)
A Matrix of species specific parameters. See rochet_GB_parameterValues
A matrix is returned
A matrix (nSize x nSpecies) of Maturity proportions. Note: Maturity = 0 for size classes in which a species does not reach.
