Details:

Using quad


quad('sin(x)',0,pi)
warning: quad: passing function body as a string is obsolete; please use
anonymous functions
ans =                    2


Using quadl


quadl('sin(x)',0,pi)
error: feval: function 'sin(x)' not found
error: called from
    quadl at line 89 column 5


Using quadl and a function

F2= @(x) sin(x);
>> quadl(F2,0,pi)
ans =                    2


The help section states I could use a string. I would anticipate the same
warning as in quad if it is obsolete.

Am I misunderstanding the help section?
