You may change the behaviour of ALGB
by clearing or setting
some user flags (and the system flag -27). Here are the most important
flags of ALGB
:
- flag 1: display flag (if set then verbose mode selected)
- flag 12: simplification flag (if set then
ALGB
calls the gcd
algorithm if needed)
- flag 13: complex flag (if cleared, all expressions are assumed
to be real and
ALGB
tries to return only real expressions)
- flag 15: real are integer flag (if set, real are assumed to be integer)
- flag 17: internal flag (if set, all data are assumed to be internal)
- flag 21: recurse flag (if set, the simplification algorithms
EXPA
and TSIMP
will simplify in subexpressions)
- system flag -27: if set, then the user representation of
complex numbers is symbolic.
To set a flag (say flag 12), type 12 SF
. To clear a flag,
type 12 CF
. To reset ALGB
flag to their defaut values
