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: RenderMeshProcessGUI.m
    path of file: ./repos/u-shape3D/software
    
    the code of the file until where you have to start completion: function varargout = RenderMeshProcessGUI(varargin)
% rendermeshprocessgui M-file for rendermeshprocessgui.fig
%      rendermeshprocessgui, by itself, creates a new rendermeshprocessgui or raises the existing
%      singleton*.
%
%      H = rendermeshprocessgui returns the handle to a new rendermeshprocessgui or the handle to
%      the existing singleton*.
%
%      rendermeshprocessgui('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in rendermeshprocessgui.M with the given input arguments.
%
%      rendermeshprocessgui('Property','Value',...) creates a new rendermeshprocessgui or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before rendermeshprocessgui_openingfcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to rendermeshprocessgui_openingfcn via varargin.
