I want to load multiple images in Matlab GUI. Algorithm below:

 % --- Executes on button press in pushbutton1.

function pushbutton1_Callback(hObject, eventdata, handles)

% hObject    handle to pushbutton1 (see GCBO)

% eventdata  reserved - to be defined in a future version of MATLAB

% handles    structure with handles and user data (see GUIDATA)

[filename path] = uigetfile('*.jpg','*.png','Chose files to 

load','MultiSelect','on');

 if isequal(filename,0) || isequal(path,0) 

return

end

if iscell(filename)

img = cell(size(filename));

for ii = 1:numel(filename)

img{ii} = imread(fullfile(path,filename{ii}));

end

else

img{1} = imread(fullfile(path,filename));

end

filename = strcat(path,filename);

fullpathname = strcat(path, filename);

set(handles.edit1,'String', fullpathname);

fileID = fopen(strcat(path, filename), 'r');

I also need the directory of an image or images to bee seen text box, but it gives me subsequent error:

Error using imread>parse_inputs (line 457)

The file name or URL argument must be a string.

Error in imread (line 316)

[filename, fmt_s, extraArgs] = parse_inputs(varargin{:});

Error in untitled>pushbutton1_Callback (line 112)

im = rgb2gray(imread(filename));

Error in gui_mainfcn (line 95)

feval(varargin{:});

Error in untitled (line 42)

gui_mainfcn(gui_State, varargin{:});

Error in 

@(hObject,eventdata)

untitled('pushbutton1_Callback',hObject,eventdata,guidata(hObject))

Could you please give me a hint, what and how I can customize the algorithm to make it functional?

One reason for the code to fail is that once you merge the filename and the path you miss a / (or depending on which OS you are working). Therefore you should use fullfile(path,filename) instead of strcat(path,filename).
