gfanFanProduct -- computes the product of polyhedral fans

Synopsis

• Usage:

  P = gfanFanProduct(F,G)

• Inputs:
  • F, an instance of the type Fan, a polyhedral fan
  • G, an instance of the type Fan, a polyhedral fan
• Optional inputs:
  • i1
  • i2
• Outputs:
  • P, an instance of the type Fan, the product of F and G
