Follow-up Comment #11, bug #60924 (project octave):
As I mentioned in comment #2, using a function handle is unusual, but allowed
syntax. Users would choose to use a function when it is easier to describe
the effects of
A * x
via a program rather than a matrix itself. In this case, where
rows=columns=1024, the matrix would take 8.3 MB as a dense array. Instead, it
takes up just the memory of a function handle which is quite small.
