Hi all, My GUI (called tts2) has an editbox and a pushbutton. By pushing the button, the pushbutton callback is supposed to scan the editbox and return the number of words written. But i'm not sure how to code the pushbutton callback to obtain the data it needs from the editbox function. Here's the code for the callback sections of the editbox and pushbutton:
function tts2_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
function varargout = tts2_OutputFcn(hObject, eventdata, handles) ;
varargout{1} = handles.output;
function editbox_Callback(hObject, eventdata, handles)
function editbox_CreateFcn(hObject, eventdata, handles)
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
set(hObject,'BackgroundColor','white');
end
function pushbutton1_Callback(hObject, eventdata, handles)
words = get(hObject, 'string');
wordsarray = textscan (words, '%s');
max_words = length(wordsarray)
disp (wordsarray)

words = get(handles.edit, 'String'); %edit is the name of the edit box
if you are using GUIDE the names of the editboxes are done consecutively (edit1,edit2,edit3...) so if you only have one editbox the name is edit1 unless you changed it.
words = get(handles.edit1, 'String');

ahh ok.
function pushbutton1_Callback(hObject, eventdata, handles)
words = get(handles.editbox, 'string');
wordsarray = textscan (words, '%s'); %this splits up the string into an array
max_words = length(wordsarray) %this is supposed to count the number of words in the array
disp (max_words)
now, no matter how many words are keyed into the editbox, the only value returned is 1, when it should actually output the number of words in the input string. i know textscan splits the string into an array of words and i suspect that its only counting one dimension (only the row or only the column, because it stores it in a 1xK array, where k is the number of words, i think). how do i make disp() display the other dimension? or is there another function to output K from a 1xK array?

wordsarray is actually a cell not one array, do this:
wordscell = textscan (words, '%s');
nwords=cellfun(@numel,wordscell);
disp (nwords)
