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.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

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

end keyword in Orient_CreateFcn, is used to end the if statement's block I guess
0

You have an extra end on line 45, just delete it. See below

    gui_mainfcn(gui_State, varargin{:});
end
end % <- this one

Thanks buddy, it sorted out that parse error. But now I'm error in line 43 saying: Error in GUI (line 43) gui_mainfcn(gui_State, varargin{:}); I'm a noobie in MatLab. @Vahe Tshitoyan
@Wolfie I know, but when you automatically generate a GUI (e.g. using guide), end is skipped for all the functions. I assume another solution would be to put the end everywhere..
Yes you need to put end everywhere (at the end of each function) because it is used within a function, see my answer! The new error is likely because of the same issue in another disguise
@StupidGuy try putting an end at the end of each function and testing it, see if it works. I do not get the same error you do on line 43, but I do not have the fig file so I cannot test it properly
@Wolfie sure, but I think end here refers to its usage to end a function, not just the end keyword in general. E.g. to end an if statement inside the function, which always requires an end.
