You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: CoreData.m
    path of file: ./repos/AI-mag/src/inductor_design/+design_compute
    
    the code of the file until where you have to start completion: classdef CoreData < handle
    % Class for managing the core material data.
    %
    %    Map the different unique id 
    
function B_sat_max = get_flux_density(self)
            % Get the maximum flux density of the component.
            %
            %    Returns:
            %        B_sat_max (vector): maximum flux density of the different samples
            
            B_sat_max = self.param.B_sat_max;
        end
