expr- any expression

Introduction

The TYP::Iss function tests whether expr is a generator of the s-basis that is a Schur function.

The indexing vector must be a partition.

Example 1

>> muEC::TYP::Iss( s[] );
                                   TRUE
>> muEC::TYP::Iss( s[3,2,2,1] );
                                   TRUE
>> muEC::TYP::Iss( s[2,3,2,1] );
