exteriorPower(ZZ,Matrix) -- exterior power

Synopsis:

  • Usage: g = exteriorPower(i,f)
  • Function: exteriorPower -- exterior power
  • Input:
  • i, an instance of class ZZ.
  • f, an instance of class Matrix.
  • Output:
  • g, an instance of class Matrix: the i-th exterior power of the matrix f.
  • Note: we may write exteriorPower_i f instead of exteriorPower(i,f); see (symbol _,Function,Thing).
