Yes, provided that all the values you want stored are strings.
You may wish to look at the UserData tag that all graphics objects have, and you may wish to look at guidata() and at setappdata() / getappdata()

If you try to set() the String as a 2D array of numeric values, it will be unhappy and may throw the values away.
If you set() the array as a vector (row or column) of numeric values, then it will convert each entry to printable form using a '%.7g' format or similar, making the list a list of strings each containing the printable representation of one sample. You can get() the String array and index into it to fetch the printable values and convert them back into numbers.
If you want to store real numeric data against an object then use UserData or one of the other suggestions I gave. The String property of uicontrol get automatically altered from numeric form as a convenience to users.
