dlmread() error After compiling.

hi

I made a program. it works with no problems when i run it on matlab windows.

However, once i try executing filename.exe after compiling m-files using mcc -m filename.m. it doesn't works.

I found the problem that is about dlmread(). this instruction can not read the 'csv'file, but i could read the 'csv' file on matlab windows as i ran it.

I don't understand why it doesn't work after compiling, because it works with no problem as i run on matlab windows.

if you guys know this problem could you tell me the reason???

Thank You.

Please post the complete line and explain, if you are using relative or absolute paths.

The likely reason is that your executable was not in the right directory.

OK ,I just made simple testfile using dlmread()

Before trying this source, you need to make folder named 'test' here (path='C:\Users\Administrator\Desktop\test\).

next, move this source and any 'csv file' named 'test.csv' that you made to test folder

where you just got made.

this source will excute pretty well on matlab wondows.

But after compfiling using mcc -m filename.m. it doesn't work if you start 'exe' file.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
function varargout = aaa(varargin)

gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @aaa_OpeningFcn, ...
                   'gui_OutputFcn',  @aaa_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

% --- Executes just before aaa is made visible.
function aaa_OpeningFcn(hObject, eventdata, handles, varargin)

handles.output = hObject;

guidata(hObject, handles);

% --- Outputs from this function are returned to the command line.
function varargout = aaa_OutputFcn(hObject, eventdata, handles) 

varargout{1} = handles.output;

% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
path='C:\Users\Administrator\Desktop\test\';

result=dlmread([path 'test.csv'],',',0,0);

csvwrite('result.csv',result);

You are not writing along the path: you are writing to whichever directory the executable happens to be in.
