RowNum -- the row of the diagonal weight matrix to permute

Synopsis

• Usage:

  Lgr = matchingFieldFromPermutation(k, n, S, RowNum => r)

  Lfl = matchingFieldFromPermutation(kList, n, S, RowNum => r)

• Inputs:
  • k, an integer,
  • kList, a list,
  • n, an integer,
  • S, a list, a permutation of $1, \dots, n$
  • r, an integer, an integer at most $k$ or at most $\max(kList)$
• Outputs:
  • Lgr, an instance of the type GrMatchingField,
  • Lfl, an instance of the type FlMatchingField,
