Automatically select a checkbox

I am new in the GUI Matlab world. What I would like to is to create a GUI that will review a plot and help select certain adjustments. I have created a small Matlab program that will review the plots and create a vector of the output. What I would like help on, is for the GUI to look at one point in the vector and preselect a checkbox for the person. The person will be able to review what has been selected and remove the checkmark if they decide it is not necessary.

% --- Executes just before StackedGUI is made visible.
function StackedGUI_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to StackedGUI (see VARARGIN)

% Choose default command line output for StackedGUI
handles.output = hObject;

%Input of file
Sen = dlmread('file.txt',',','A3..G803');
nom = dlmread('textn.txt',',','A3..G803');
Senestive_help;

%Plotting to Axis
axes(handles.axes1)
plot(nom(:,1),nom(:,2),Sen(:,1),Sen(:,2));
xlabel('Time (sec)');
ylabel('X (ft)');
title('X');
grid on

axes(handles.axes2)
plot(nom(:,1),nom(:,3),Sen(:,1),Sen(:,3));
xlabel('Time (sec)');
ylabel('Y (ft)');
title('Y');
grid on

axes(handles.axes3)
plot(nom(:,1),nom(:,4),Sen(:,1),Sen(:,4));
xlabel('Time (sec)');
ylabel('Z (ft)');
title('Z');
grid on

axes(handles.axes4)
plot(nom(:,1),nom(:,5),Sen(:,1),Sen(:,5));
xlabel('Time (sec)');
ylabel('Psi (deg)');
title('Psi');
grid on

axes(handles.axes5)
plot(nom(:,1),nom(:,6),Sen(:,1),Sen(:,6));
xlabel('Time (sec)');
ylabel('Theta (deg)');
title('Theta');
grid on

axes(handles.axes6)
plot(nom(:,1),nom(:,7),Sen(:,1),Sen(:,7));
xlabel('Time (sec)');
ylabel('Phi (deg)');
title('Phi');
grid on

% Update handles structure
guidata(hObject, handles);

% UIWAIT makes StackedGUI wait for user response (see UIRESUME)
% uiwait(handles.figure1);

% --- Outputs from this function are returned to the command line.
function varargout = StackedGUI_OutputFcn(hObject, eventdata, handles) 
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Get default command line output from handles structure
varargout{1} = handles.output;

% --- Executes on button press in checkbox1.
function checkbox1_Callback(hObject, eventdata, handles)
% hObject    handle to checkbox1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Hint: get(hObject,'Value') returns toggle state of checkbox1
if a1(1)>= 1;
    (get(hObject,'Value') == get(hObject,'Max'));
end

Senestive_help creates a vector (which is mentioned above) a1. This vector will help determine whether or not the checkbox should be selected or not. Where in the checkbox1 will bring up one point in the vector to see if the value is one or greater and check the box.

Example vector a1=[1 0 3 2 0]

For this example, checkbox1 should be automatically selected since a1(1)>=1.

Any help would be appreciated.

Set the value of it:

checkbox = uicontrol('style','checkbox');
set(checkbox,'Value',true)

Since you're using GUIDE, you'll need to apply this to the checkboxes in handles

Sorry for the delay response. This is what I have placed underneath the place for the checkbox1 position.

a1=[1 0 0 1];

if a1(1)==1;
       checkbox=uicontrol('Style','checkbox1');
       set(checkbox,'Vaule',true);
end

I am assuming this is incorrect since the code is not automatically input the check mark in the appropriate box.

[Sean de Wolski]

It'll be something like

set(handles.checkbox1,'Value',true)

But you have a typo above and you're adding a new uicontrol which is not what I suspect you want to do.

Perfect, I appreciate the help.
