This demo based on "Kailup Tan" works about handwriting recognition this version is more compatible and support Farsi/Arabic digit,
u can take some change for add other handwriting pattern it's so easy too use taste it

how to run this code

The code need to be improved as newff is replaced by feedforwadnet in new matlab version.

The algorithm behind, is a simple neural network. Basically, the images are resized to 7x5 pixcels (the crossed blue squares); then a NN is trained based on the traning data. The same procedure is applied on the test data, and finally the model predict the test

Could you please explain how the recognition part is working..
Can we change the selected_ln and selected_col dynamically in the code?

Not work.

when I select "select"
he write error

??? Error using ==> axes
Invalid object handle.

Error in ==> odrfr>pushbutton2_Callback at 102
axes(handles.axes2);

Error in ==> gui_mainfcn at 75
feval(varargin{:});

Error in ==> odrfr at 42
gui_mainfcn(gui_State, varargin{:});

??? Error while evaluating uicontrol Callback.
