I'm getting this unwanted parse error saying
Error: File: GUI.m Line: 284 Column: 5. Unexpected MATLAB operator.
However, I cannot see any unexpected operator. Can anybody diagnose this issue?
Here's my code:
function varargout = GUI(varargin)
% GUI MATLAB code for GUI.fig
% GUI, by itself, creates a new GUI or raises the existing
% singleton*.
%
% H = GUI returns the handle to a new GUI or the handle to
% the existing singleton*.
%
% GUI('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in GUI.M with the given input arguments.
%
% GUI('Property','Value',...) creates a new GUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before GUI_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to GUI_OpeningFcn via varargin.

From the Matlab documentation:
Functions end with either an end statement, the end of the file, or the definition line for a local function, whichever comes first. The end statement is required if:
Any function in the file contains a nested function (a function completely contained within its parent).
The function is a local function within a function file, and any local function in the file uses the end keyword.
The function is a local function within a script file.
You use the end keyword in your function Orient_CreateFcn, so all of your local functions require an end statement.
This is good coding practise anyway, as it makes your code more clear. For example it clarifies whether a local function is nested or not without having to find the parent function's end
You have an extra end on line 45, just delete it. See below
gui_mainfcn(gui_State, varargin{:});
end

I have two GUI's with the figure-tags mainWindow and annotatorWindow. I want to pass data between the two windows. When I copy the data from mainWindow to annotatorWindow (see copyData_Callback), it works perfectly. But when I want to write the data back to mainWindow (see saveData_Callback), I get the error "Matrix indices must be full double". I'm not entirely sure what this even means, any help is appreciated. The code of interest is below.
CALLBACKS UNDER annotatorWindow
% --- Executes on button press in copyData.
function copyData_Callback(hObject, eventdata, handles)
% hObject handle to copyData (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
h = findobj('Tag', 'mainWindow');
if ~isempty(h)
pData = guidata(h)
handles.UserData = pData.UserData
end
guidata(hObject, handles);
return
% --- Executes on button press in saveData.
function saveData_Callback(hObject, eventdata, handles)
% hObject handle to saveData (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB

if ~isempty(h)
guidata(h).UserData = handles.UserData
end
guidata(hObject, handles);
return
Figured it out! To pass data between two GUI's, you can only ever pull data from a GUI. You can never write data to a GUI from another GUI. I created a function in mainWindow called saveData (see below). I then called the saveData function from annotatorWindow allowing me to pass data back and forth.
mainWindow
function saveData(hObject, handles)
h = findobj('Tag', 'annotatorWindow');
if ~isempty(h)
aData = guidata(h)
handles.UserData = aData.UserData
end
guidata(hObject, handles);

There are several ways to do this, but maybe a good way is to store the image (after applying a filter) in the figure's application data. You can do this with guidata.
After each filter you store the image;

I'm new to this forum and to matlab GUIs. I have this problem. I wanted to create a GUI which allows you to load data from an xlsx file and then I'd like to compute a GARCH model with this data. The problem I have is that I don't know how to pass this data to the function GARCH.
These are the functions I wrote. Hope you can help me.
function open(handles)
[FileName, PathName] = uigetfile('*.xlsx', 'Seleziona File dei Rendimenti');
A = xlsread(FileName, -1);
inVdati = A(:);
plot(inVdati, 'r');
legend('returns');
set(handles.Variance, 'Enable', 'on');
guidata(handles.figure1, handles) %saving values
and
function garch(handles)
handles = guidata(handles.figure1);
Sigmas = [];
spec = garchset('P', 1, 'Q', 1);
[Coeff, Errors, LLF, Innovations, Sigmas] = garchfit(spec, handles);
Can anyone of you tell me where I'm wrong?
Thank u :)

When I press load button, it shows a dialouge box for selecting files. After selecting files how can i extract datapoints written in the file, to plot a graph.
Your callback function to load the contents of the is load_Callback, I assume:
% --- Executes on button press in load.
function load_Callback(hObject, eventdata, handles)
[filename, pathname] = uigetfile({'*.*'},'Open Directory');
if isequal(filename,0) || isequal(pathname,0)
return
end
guidata(hObject, handles);
uigetfile returns the name of the selected file and its path. It does not read or load it.
First, you need to open the file using fopen.
If the file extension is txt, you can use functions like textscan or fscanf.
If the file extension is dat, you can use fread.
Example for txt file:
% --- Executes on button press in load.
function load_Callback(hObject, eventdata, handles)
[filename, pathname] = uigetfile({'*.*'},'Open Directory');
if isequal(filename, 0) || isequal(pathname, 0)
return
end
fileID = fopen(strcat(pathname, filename), 'r'); % read-only permission
handles.fileData = textscan(fileID,'%d');
guidata(hObject, handles);
Then, you can access handles.fileData from any of your callback functions.
