The following is found from octave pdf document. They can be readily
added to help('@').

A function handle is a pointer to another function and is defined with
the syntax
@function-name
For example,
f = @sin;
creates a function handle called f that refers to the function sin.
Function handles are used to call other functions indirectly, or to
pass a function as an
argument to another function like quad or fsolve. For example:
f = @sin;
quad (f, 0, pi)
) 2
You may use feval to call a function using function handle, or simply
write the name
of the function handle followed by an argument list. If there are no
arguments, you must
use an empty argument list ‘()’. For example:
f = @sin;
feval (f, pi/4)
) 0.70711
f (pi/4)
) 0.70711
