Set does not have any output arguments, thus call set(T_old, 'String', 'New Title');
without any return variables.

سؤال
I'm writing a function which ought to plot to an already created axes. The function provides the option to re-title the axes, and I'm trying to make that functionality work.
If the axes doesn't already have a title then just calling title() works, of course.
But: If the axes does already have a title, then calling title() overprints the original title, but leaves the original in place.
So: I've been experimenting with set():
T_old = get(gca, 'Title');
T_new = set(T_old, 'String', 'New Title');
Which leaves me the error message:
One or more output arguments not assigned during call to "set".
What am I doing wrong? Are there other arguments which must be set for the Title handle? And if so what?

From the help for set
:
A = set(H, 'PropertyName')
set(H,'PropertyName')
returns or displays the possible values for the specified property of the object with handle H. The returned array is a cell array of possible value strings or an empty cell array if the property does not have a finite set of possible string values.
However, you're calling set
and and actually setting a property value. This is not a valid input pattern. Just call this instead:
set(T_old, 'String', 'New Title');
