D.13.3.30 tDetropicalise
Procedure from library tropical.lib (see tropical_lib).
- Usage:
- tDetropicalise(f); f poly or f list
- Assume:
- if f is of type poly then f is a linear polynomial with an
integer constant term and positive integer coefficients
as further coefficients;
if f is of type list then it is a list of polynomials of
the type just described in before
- Return:
- poly, the detropicalisation of f over the field Q(t)
- Note:
- the output will be a term where the coeffiecient is a Laurent
monomial in the variable t
Example:
| | LIB "tropical.lib";
ring r=(0,t),(x,y),dp;
tDetropicalise(3x+4y-1);
