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: MultigraphBUD.m
    path of file: ./repos/BRAPH-2/braph2/graphs
    
    the code of the file until where you have to start completion: classdef MultigraphBUD < GraphWU
	%MultigraphBUD is
    
function value = calculateValue(g, prop, varargin)
			%CALCULATEVALUE calculates the value of a property.
			%
			% VALUE = CALCULATEVALUE(EL, PROP) calculates the value of the property
			%  PROP. It works only with properties with 5,
			%  6, and 7. By default this function
			%  returns the default value for the prop and should be implemented in the
			%  subclasses of Element when needed.
			%
			% VALUE = CALCULATEVALUE(EL, PROP, VARARGIN) works with properties with
			%  6.
			%
			% See also getPropDefaultConditioned, conditioning, preset, checkProp,
			%  postset, postprocessing, checkValue.
			
			switch prop
				case 10 % MultigraphBUD.CONNECTIVITY_TYPE
					if isempty(varargin)
					    layernumber = 1;
					else
					    layernumber = varargin{1};
					end
