Create structure of handles
handles = guihandles(object_handle)
handles = guihandles
handles = guihandles(object_handle) returns
a structure containing the handles of the objects in a figure, using
the value of their
Tagproperties as the field names, with
the following caveats:
Objects are excluded if their
are empty, or are not legal variable names.
If several objects have the same
that field in the structure contains a vector of handles.
Objects with hidden handles are included in the structure.
handles = guihandles returns
a structure of handles for the current figure.
