SG::RRep2Perm --
calculates a permutation from its matrix in the regular
representation
Call(s)
SG::RRep2Perm(m)
Parametersm | - | a square matrix |
Introduction
The SG::RRep2Perm function calculates a permutation from its matrix in
the regular representation, that is to say the matrix of the linear
operator "left multiplication by perm".
Example 1>> muEC::SG::Perm2RRep( [3,1,2] );
