Unrecognized function or variable 'pushbutton1_Callback'.
Error in gui_mainfcn (line 95)
feval(varargin{:});
Error in Gui_Main (line 42)
gui_mainfcn(gui_State, varargin{:});
Error in
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)Gui_Main('pushbutton1_Callback',hObject,eventdata,guidata(hObject))
95 feval(varargin{:});
this is my gui code
function varargout = Gui_Main(varargin)
% GUI_MAIN MATLAB code for Gui_Main.fig
% GUI_MAIN, by itself, creates a new GUI_MAIN or raises the existing
% singleton*.
%
% H = GUI_MAIN returns the handle to a new GUI_MAIN or the handle to
% the existing singleton*.
%
% GUI_MAIN('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in GUI_MAIN.M with the given input arguments.
%
% GUI_MAIN('Property','Value',...) creates a new GUI_MAIN or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Gui_Main_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Gui_Main_OpeningFcn via varargin.

Inside Gui_Main.fig there is a graphics object that asks Gui_Main to execute function pushbutton1_Callback. However, your Gui_Main.m file does not define any function named pushbutton1_Callback . It does define a function named pushbuttonOpenFile_Callback but that does not necessarily have anything to do with pushbutton1_Callback .
I suspect that you tried to rename a pushbutton callback function by just editing the Gui_Main.m code . You cannot do that: you have to use GUIDE to change the callback it associates with the button.
There is state information stored in the .fig file that is not stored in the .m file; you need to work with the two together.
For the moment, you could experiment by adding
function pushbutton1_Callback(hObject, eventdata, handles)
pushbuttonOpenFile_Callback(hObject, eventdata, handles);
end
This would have pushbutton1_Callback just immediately invoke pushbuttonOpenFile_Callback .
... Assuming that is the desired behaviour.
