OldToricVectorBundles :: rays(ToricVectorBundle)

rays(ToricVectorBundle) -- the rays of the underlying fan

Synopsis

Description

Returns the rays of the fan of the underlying toric variety as a list. Each ray is given as a one column matrix.

i1 : E = cotangentBundle projectiveSpaceFan 2

o1 = {dimension of the variety => 2 }
      number of affine charts => 3
      number of rays => 3
      rank of the vector bundle => 2
