guide help import workspace

How I can import a variable of my workspace into a line to my guide *.m

function btnSaltaPepper_Callback(hObject, eventdata, handles)
set(handles.truido,'string','Salt & Pepper Noise')
axes(handles.iruido);
J = imnoise(I,'salt & pepper');
imshow(J,'InitialMagnification','fit')
assignin('base','J',J)

I need import I from my workspace for apply the imnoise

Thanks

I = evalin('base','I');

Provided, that is, that you put I in the base workspace to begin with. There are a lot of other workspaces you might have put it in.

Nik - you could put this code in either the _CreateFcn for the uitable, or the _OpeningFcn of your GUI. If the former, then the code would be something like

 function uitable1_CreateFcn(hObject, eventdata, handles)
 % check to see if the variable exists in the base workspace
 if evalin('base','exist(''Table'',''var'')')
    % get the variable from the base workspace and save it to the table
    data = evalin('base','Table');
    set(hObject,'Data',data);
 end

The above code would be near-identical for the _OpeningFcn - all you would have to do is replace hObject with handles.uitable1.

Note how the above code checks to see if the variable exists before trying to access it using evalin.

In the above example, Table was created in the workspace as

 Table = randi(255,12,4);

You have a typo in the noise type - it should be pepper and not papper. Try the following instead

 imnoise(k,'salt & pepper',0.02);
