TYP::Ise --
tests whether the argument is a product of generators of the
e-basis
Call(s)
TYP::Ise(expr)
Parametersexpr | - | any expression |
Introduction
The TYP::Ise function tests whether expr is a product of generators of
the e-basis that is a product of elementary symmetric functions.
The indexing vector must be a partition.
Example 1>> muEC::TYP::Ise( e[] );
TRUE
>> muEC::TYP::Ise( e[3,2,2,1] );
TRUE
>> muEC::TYP::Ise( e[2,3,2,1] );
FALSE
