D.15.18.1 realizationDim
Procedure from library realizationMatroids.lib (see realizationMatroids_lib).
- Usage:
- realizationDim(I,C); where I is a homogeneous linear ideal defining the projective plane Y = V(I) and C is a list of intvectors such that each intvector represents a one-dimensional cone in the tropical fan curve whose relative realizability should be checked. This representation is done in the following way: the one-dimensional cone K is represented by a vector w whose equivalence class [w] in R^n/<1> can be written as [w] = m*[v] where [v] is the primitive generator of K and m is the weight of K.
- Returns:
- the dimension of the relative realization space of the tropical curve C with respect to Y, and -1 if the relative realization space is empty.
