I have a cellArray data and I extracted the first column of this cellArray. In another function when I call this data with global this data looks empty.

function pushbutton1_Callback(hObject, eventdata, handles)

.............

cellArray=

    ' 334      4261461.0645      2661117.6797      3918916.0472'

    ' 352       4266205.852        2659683.96      3914798.2885'

    ' 404      4258400.8221       2662966.354       3920634.872'

out1 = regexp(cellArray,'(?<=^\s*)\d*','match')

out1= cat(1,out1{:})

function pushbutton2_Callback(hObject, eventdata, handles)

global out1

%when I call out1 it looks []. It should look

'334'

'352'

'404'

what is the problem?

Avoid global, you can use for example guidata

function pushbutton1_Callback(hObject, eventdata, handles)
handles.out1=out1
guidata(handles,hObject)

In the second pushbutton

function pushbutton2_Callback(hObject, eventdata, handles)
out1=handles.out1

I see no GLOBAL in pushbutton1_Callback where out1 is defined. And, of course, even if there were, it has to have been executed first.
