How can I save string data as double in Userdata GUI?
显示 更早的评论
I am working with radiobuttons in Matlab GUI. I want that everytime I press a radiobutton, a word stored in the UserData box prints using fprintf. I have the fprintf part figured out, however, I have been trying to save the words using the inspector UIcontrol window for every radiobutton but it doesn't work. Any help?
Thanks!

At the MATLAB command line, take the string you want and double() it, such as
double('this is the first string')
The result will be a vector of numbers that you should be able to store.
Then when it comes time to fprintf() the userdata,
TheUserData = get(hObject, 'UserData');
fprintf('%s', char(TheUserData));
