How can I use local variable from GUI (from subroutine to another subroutine in a main function)

How can I use local variable from GUI? I want to use from subroutine to another subroutine in a main function. For example,

function bio=bio_analysis(data1,data2) % my main function

......

....

[option1 option2 option3]= checkbox % my 1st subroutine (This subroutine was created from GUI as shown at the end. I failed this step. I couldn't get option1,option2,and option3 from this subroutine to use for another subroutine)

[info1 info2]= calculation(data1,data2) % 2nd subroutine

....

...

and so on.

end

How could I fix this problem? Thank you.

What's more, I tried to put 2nd subroutine into 1st one(in checkbox) like this (last function in my checkbox subroutine)

function pushbutton1_Callback(hObject, eventdata, handles,data1,data2) % I can't call the data1 and data2 from main function in this subroutine even though I put it in the argument so this function failed!

if checkboxvalue1==1

    [data_a]=bottomplane(data1);
else

end

if checkboxvalue2==1

    [data_b]=scape_bottom(data2);
else

end

Note: FYI; my checkbox code (GUI)

function varargout = checkbox3(varargin)

% Begin initialization code - DO NOT EDIT gui_Singleton = 1; gui_State = struct('gui_Name', mfilename, ... 'gui_Singleton', gui_Singleton, ... 'gui_OpeningFcn', @checkbox3_OpeningFcn, ... 'gui_OutputFcn', @checkbox3_OutputFcn, ... 'gui_LayoutFcn', [] , ... 'gui_Callback', []); if nargin && ischar(varargin{1}) gui_State.gui_Callback = str2func(varargin{1}); end

if nargout [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:}); else gui_mainfcn(gui_State, varargin{:}); end % End initialization code - DO NOT EDIT

% --- Executes just before checkbox3 is made visible.

function checkbox3_OpeningFcn(hObject, eventdata, handles, varargin)

% Choose default command line output for checkbox3

handles.output = hObject;

% Update handles structure

guidata(hObject, handles);

% --- Outputs from this function are returned to the command line.

function varargout = checkbox3_OutputFcn(hObject, eventdata, handles)

% Get default command line output from handles structure

varargout{1} = handles.output;

% --- Executes on button press in checkbox1.

function checkbox1_Callback(hObject, eventdata, handles)

chk1=get(hObject,'Value');

% --- Executes on button press in checkbox2.

function checkbox2_Callback(hObject, eventdata, handles)

chk2=get(hObject,'Value');

% --- Executes on button press in checkbox3.

function checkbox3_Callback(hObject, eventdata, handles)

chk3=get(hObject,'Value');

% --- Executes on button press in pushbutton1.

function [O1 O2 O3]= pushbutton1_Callback(hObject, eventdata, handles)

checkboxValues(1) = get(handles.checkbox1, 'value');

checkboxValues(2) = get(handles.checkbox2, 'value');

checkboxValues(3) = get(handles.checkbox3, 'value');

O1=checkboxValues(1); %bottomplan O2=checkboxValues(2); %scape_bottom O3=checkboxValues(3); %despeck2

close all

if O1==1

    [data1]=bottomplane(data);

else

end

if O2==1

    [data2]=scape_bottom(data);

else

end

Use guidata. for example to communicate y to other functions

y=10
handles.y=y
guidata(hObject, handles);

%to get y

y=handles.y

Thanks a lot! I tried this solution but these was a error. Please take a look what I did.

function bio=bion_ana % main function

....

....

checkbox % my subroutine ( I called my subroutine this step)

O1=handles.O1 ( it showed "??? Undefined variable "handles" or class "handles.O1"." it seemed that after it finished subroutine, checkbox, then it cleared handles so it can't get O1 from subroutine so please give me some advice)

note: in checkbox code

O1=checkboxValues(1);

O2=checkboxValues(2);

O3=checkboxValues(3);

handles.O1=O1;

handles.O2=O2;

handles.O3=O3;

guidata(hObject,handles);

The name of your function should be

function checkbox1_Callback(hObject, eventdata, handles)

% handles should be in input argument of your functions

[Nopparat]

I'm not sure whether I correctly understand or not. In my code, I have only 1 main function and other functions are subroutine that I didn't use function command. For example,

function bio=ana_bio(data1,data2) % this is my main function that use function command

[info1 info2]= calculate1(data1,data2) % my subroutine (for my subroutine I didn't use function command)

[info3 info4]= calculate2(info1,info2)

[o1 o2 o3]= checkbox3 % this subroutine is my problem because I use gui and I can't get o1 o2 and o3 from this subroutine.

So do I need to input like this [o1 o2 o3]= checkbox3(hObeject, eventdat, handles) ? or something else? I'm so confused about gui. This is my first time to use gui. I tried to read information and some examples but I still didn't get it. Thank you very much for your help. I really appreciate it

[Azzi Abdelmalek]

If you need O1 in your function calculate1, add handles to your input argument

[info1 info2]= calculate1(data1,data2,handles)
o1=handles.O1
