[Maxima-discuss] rule issue

[Dimiter P. <dim...@gm...>]

Dear all,

I have a problem with the following rule

(matchdeclare (u, atom, fn, symbolp),
defrule (ddint21, 'integrate(delta(u)*fn(u), u, minf, inf), fn(0))
);


>> ddint21('integrate(delta(u)*fn(u), u, minf, inf));
output false
should be
fn(0)

I tried playing around relaxing the match but even with true true it
doesn't work.

Any ideas?

best regards,

Dimiter
