MATLAB: Struct contents reference from a non-struct array object `

javamatlab functionmatlab guiuitable

I'm converting a script into function and getting the following error:

    Struct contents reference from a non-struct array object.
    Error in button_callback_2 (line 16)
    out=cellfun(@str2num,myData.toArray.cell,'un',0)';
     Error while evaluating UIControl Callback.
The class of myData is a java.util.vector

Without making function, the script does the intended work.

I don't know what myData is, but if it's an edit field on your GUI created with GUIDE, then to get the string in it, you can do

out = handles.myData.String;

MATLAB: How to pass a struct between callbacks in GUI

Valentino - just save the structure to handles in one callback so that the other callback has access to it. For example, if the following is the callback to choose and load the contents of a file

 function pushbutton1_Callback(hObject, eventdata, handles)
 % choose the file
 % load the data into a structure myData
 % add the structure to handles
 handles.myData = myData;
 % save the updated structure
 guidata(hObject,handles);

Now in your other callback, you can access this structure directly as

 function pushbutton2_Callback(hObject, eventdata, handles)
 if isfield(handles,'myData')
     % do something with myData
 end

Try implementing the above and see what happens!

out = [data.bidPrice]

out = cat(1,data.bidPrice)
