Error in gui_mainfcn (line 220) feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});Error in untitled1 (line 42) gui_mainfcn(gui_State, varargin{:});MATLAB: This error happens when i press the run button . I used the matlab gui pushbutton to control arduino led.pls help me.

In your callback for edit1 you replace the handle with the value extracted from the handle. That is confusing at the very least.
Hi,
it is possible to do with small trick.
When passing data between GUIs, the idea is via MAT file.
I have 2 GUIs as shown in picture below :
In the first GUI, button 'Threshold' will execute second GUI.
In second GUI, you should threshold the image by changing the slider position and then click OK.
The thresholded image will appears in axes1 of first GUI.
Just try it. I will not explain more.
You should design the GUIs and here the code :
FIRST GUI
-------------------
function varargout = untitled(varargin)gui_Singleton = 1;gui_State = struct('gui_Name', mfilename, ... 'gui_Singleton', gui_Singleton, ... 'gui_OpeningFcn', @untitled_OpeningFcn, ... 'gui_OutputFcn', @untitled_OutputFcn, ... 'gui_LayoutFcn', [] , ... 'gui_Callback', []);if nargin && ischar(varargin{1}), gui_State.gui_Callback = str2func(varargin{1}); endif nargout, [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});else, gui_mainfcn(gui_State, varargin{:}); endfunction untitled_OpeningFcn(hObject, eventdata, handles, varargin)handles.output = hObject;handles.I = imread('cameraman.tif');imshow(handles.I);guidata(hObject, handles);function varargout = untitled_OutputFcn(hObject, eventdata, handles) varargout{1} = handles.output;function pushbutton1_Callback(hObject, eventdata, handles)handles.output = hObject;tempImg = handles.I;save('temp.mat','tempImg','-append');uiwait(untitled2);load('temp.mat');handles.I = tempbw;imshow(handles.I);guidata(hObject, handles);SECOND GUI
-------------------
function varargout = untitled2(varargin)gui_Singleton = 1;gui_State = struct('gui_Name', mfilename, ... 'gui_Singleton', gui_Singleton, ... 'gui_OpeningFcn', @untitled2_OpeningFcn, ... 'gui_OutputFcn', @untitled2_OutputFcn, ... 'gui_LayoutFcn', [] , ... 'gui_Callback', []);if nargin && ischar(varargin{1}), gui_State.gui_Callback = str2func(varargin{1}); endif nargout, [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});else, gui_mainfcn(gui_State, varargin{:}); endfunction untitled2_OpeningFcn(hObject, eventdata, handles, varargin)handles.output = hObject;load temp.mathandles.I = tempImg;handles.bw = handles.I;imshow(handles.I);set(handles.slider1,'min',0,'max',1,'sliderstep',[.1 .1]);guidata(hObject, handles);function varargout = untitled2_OutputFcn(hObject, eventdata, handles) varargout{1} = handles.output;function slider1_Callback(hObject, eventdata, handles)handles.output = hObject;thresh = get(handles.slider1,'value');handles.bw = im2bw(handles.I,thresh);imshow(handles.bw);guidata(hObject, handles);function slider1_CreateFcn(hObject, eventdata, handles)if isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor')) set(hObject,'BackgroundColor',[.9 .9 .9]);endfunction pushbutton1_Callback(hObject, eventdata, handles)handles.output = hObject;tempbw = handles.bw;save('temp.mat','tempbw','-append');close(untitled2);function pushbutton2_Callback(hObject, eventdata, handles)close(untitled2);I hope this clear.
