How can I get the numbers from GUI edit text in the contex like (1,2,3) ?

(get(handles.initial_point,'String'));
what should I add here ?

[Walter Roberson]

S = strtrim(get(handles.initial_point,'String'));
nums = str2double(regexp(S, '[\s,]+', 'split'))

This allows spaces and/or commas between the numbers so '1,2,3' and '1, 2, 3' and '1 2 3' would all be accepted.

As written it does not allow [] or () in the text. Also, if the user were to use '1,,3' trying to indicate that they want to skip the second value, then the code above would not notice that multiple commas had been used and would treat it the same as '1,3'
