SFA::Sf2SfA --
from SYMF objects to SFA objects
Call(s)
SFA::Sf2SfA(sf <,alphab>)
Parameterssf | - | any valid expression in SYMF |
alphab | - | any alphabet |
IntroductionThe SFA::Sf2SfA function transforms any symmetric function of
the package into an object of
SYMFSFA for a specific alphabet (by default A1).
Valid bases for symmetric functions are e, h, p, s, m.
Allowed alphabet expressions are linear combinations of formal
alphabets A1, A2, A3, .... For instance
3/2*A1 - A3 + 3/4 is valid.
The inverse function is SfA2Sf.
Example 1>> muEC::SFA::Sf2SfA( s[3,1]*p[2] - e[2,1] );
p[2](A1) s[3, 1](A1) - e[2, 1](A1)
>> muEC::SFA::Sf2SfA( s[3,1]*p[2] - e[2,1], A2 );
p[2](A2) s[3, 1](A2) - e[2, 1](A2)
>> muEC::SFA::Sf2SfA( s[2,2], 2*A3 );
s[2, 2](2 A3)
