Reference to non-existent field 'text1'.

Hi guys, I try to create a GUI calculator for my assigment, And i wrote code but i have a couple of errors, i cant solve any of them, please help me, here is my codes and errors ;

function varargout = text1(varargin)

% TEXT1 MATLAB code for text1.fig

% TEXT1, by itself, creates a new TEXT1 or raises the existing

% singleton*.

%

% H = TEXT1 returns the handle to a new TEXT1 or the handle to

% the existing singleton*.

%

% TEXT1('CALLBACK',hObject,eventData,handles,...) calls the local

% function named CALLBACK in TEXT1.M with the given input arguments.

%

% TEXT1('Property','Value',...) creates a new TEXT1 or raises the

% existing singleton*. Starting from the left, property value pairs are

% applied to the GUI before text1_OpeningFcn gets called. An

% unrecognized property name or invalid value makes property application

% stop. All inputs are passed to text1_OpeningFcn via varargin.

%

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one

% instance to run (singleton)".

%

% See also: GUIDE, GUIDATA, GUIHANDLES

% Edit the above text to modify the response to help text1
