function varargout = Ejem(varargin)
% EJEM MATLAB code for Ejem.fig
%      EJEM, by itself, creates a new EJEM or raises the existing
%      singleton*.
%
%      H = EJEM returns the handle to a new EJEM or the handle to
%      the existing singleton*.
%
%      EJEM('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in EJEM.M with the given input arguments.
%
%      EJEM('Property','Value',...) creates a new EJEM or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Ejem_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Ejem_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

Y me da error acá:

Error in gui_mainfcn (line 95)

Error in Ejem (line 42)
gui_mainfcn(gui_State, varargin{:});

Error in
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)Ejem('pushbutton1_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating UIControl Callback.
