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: NNxMLP_xPP_FI_Graph.m
    path of file: ./repos/BRAPH-2/braph2/neuralnetworks
    
    the code of the file until where you have to start completion: classdef NNxMLP_xPP_FI_Graph < PanelProp
	%NNxMLP_xPP_FI_Graph plots the panel of a prop cell.
	% It is a subclass of <a href="matlab:help PanelProp">PanelProp</a>.

	% A Cell Prop Panel (NNxMLP_xPP_FI_Graph) plots the panel for a CELL prop with a table and two sliders.
	% It 
    
function prop = getPropProp(pointer)
			%GETPROPPROP returns the property number of a property.
			%
			% PROP = Element.GETPROPPROP(PROP) returns PROP, i.e., the 
			%  property number of the property PROP.
			%
			% PROP = Element.GETPROPPROP(TAG) returns the property number 
			%  of the property with tag TAG.
			%
			% Alternative forms to call this method are (POINTER = PROP or TAG):
			%  PROPERTY = PR.GETPROPPROP(POINTER) returns property number of POINTER of PR.
			%  PROPERTY = Element.GETPROPPROP(NNxMLP_xPP_FI_Graph, POINTER) returns property number of POINTER of NNxMLP_xPP_FI_Graph.
			%  PROPERTY = PR.GETPROPPROP(NNxMLP_xPP_FI_Graph, POINTER) returns property number of POINTER of NNxMLP_xPP_FI_Graph.
			%
			% Note that the Element.GETPROPPROP(PR) and Element.GETPROPPROP('NNxMLP_xPP_FI_Graph')
			%  are less computationally efficient.

			% See also getPropFormat, getPropTag, getPropCategory, getPropDescription,
