BigObject LinesInCubic<Addition>

from application tropical

This represents the result of the method lines_in_cubic. It contains: The tropical polynomial representing the surface, the surface itself as a Cycle and lists of lines and families of different types, each starting with LIST_… The object also has methods, starting with array_… that return the corresponding LIST_… as a perl array. The different (lists of) lines can be visualized nicely with visualize_in_surface.

Type Parameters:

Addition: Mode of tropical addition, must be Min or Max. There is on purpose no default value for it.
