MATLAB: Can anyone fix this issue

call backpushbuttonuicontrol

   gui_mainfcn(gui_State, varargin{:});
Error in @(hObject,eventdata)plz('pushbutton1_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating UIControl Callback
and my code is
function varargout = plz(varargin)
% Begin initialization code - DO NOT EDIT
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @plz_OpeningFcn, ...
                   'gui_OutputFcn',  @plz_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

% 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 pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)

[c, d] = uigetfile({'*.*' , 'all files'});
imj = imread([c , d]);
s = imshow(imj , 'parent' , handles.axes1);
imshow(s);

Best Answer

The order of outputs from uigetfile is file name first and then directory. Your use of [c , d] has the components in the wrong order.
What you should use instead of [c, d] is fullfile(d, c)
filename = fullfile(d, c);
imj = imread(filename);
