Here's what I see when I load a file or batch it:
(C1) block([sd,t,y ],
matchdeclare([sd,t,y],true),
print(tellsimp('diff(II(sd,t),t,2),0)),
print(tellsimp('diff(II(sd,t),t),sd/ID(t))),
print(tellsimp('diff(II(sd,t),sd),0)))$
[DERIVATIVERULE1, SIMPDERIV]
[DERIVATIVERULE2, DERIVATIVERULE1, SIMPDERIV]
[DERIVATIVERULE3, DERIVATIVERULE2, DERIVATIVERULE1, SIMPDERIV]
(C2) build_info();
Maxima version: 5.9.0
Maxima build date: 19:10 2/9/2003
host type: i686-pc-mingw32
lisp-implementation-type: Kyoto Common Lisp
lisp-implementation-version: GCL-2-5.0
Suppose, besides may package, user tellsimps more and more. How do I
chop down my rules precisely??? I could possibly take the head of the
list every time I do tellsimp. But why do these two cases differ, yours
and mine?
(C3) tellsimp(f(sd),sd+1);
(D3) [fRULE1, FALSE]
(C4) tellsimp(f2(s3d),sd+1);
(D4) [f2RULE1, FALSE]
So, there seems to be a different behaviour between command line and
loading a file?
