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: Spectrogram_Topog.m
    path of file: ./repos/EEGapp/EEGapp/Spectrogram and Topographic Map
    
    the code of the file until where you have to start completion: function varargout = Spectrogram_Topog(varargin)
% SPECTROGRAM_TOPOG MATLAB code for Spectrogram_Topog.fig
%      SPECTROGRAM_TOPOG, by itself, creates a new SPECTROGRAM_TOPOG or raises the existing
%      singleton*.
%
%      H = SPECTROGRAM_TOPOG returns the handle to a new SPECTROGRAM_TOPOG or the handle to
%      the existing singleton*.
%
%      SPECTROGRAM_TOPOG('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in SPECTROGRAM_TOPOG.M with the given input arguments.
%
%      SPECTROGRAM_TOPOG('Property','Value',...) creates a new SPECTROGRAM_TOPOG or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Spectrogram_Topog_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Spectrogram_Topog_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
