topeField -- Constructor of a tope field

Synopsis

• Usage:

  TF = topeField MF

  TF = topeField(MF, T)

• Inputs:
  • MF, an instance of the type GrMatchingField, matching field containing the tuples of the tope field
  • T, a list, the type of the tope field
• Outputs:
  • TF, an instance of the type TopeField,

Description

i1 : MF = diagonalMatchingField(3,6);

i2 : TF = topeField MF

o2 = Tope field: n = 6 and type = {1, 1, 1}

o2 : TopeField

i3 : TF' = topeField(MF, {2,1})

o3 = Tope field: n = 6 and type = {2, 1}

o3 : TopeField
