D.13.6.20 texDrawBasic
Procedure from library tropical.lib (see tropical_lib).
- Usage:
- texDrawBasic(texdraw); list texdraw
- Assume:
- texdraw is a list of strings representing texdraw commands
(as produced by texDrawTropical) which should be embedded into
a texdraw environment
- Return:
- string, a texdraw environment enclosing the input
- Note:
- is called from conicWithTangents
Example:
| LIB "tropical.lib";
ring r=(0,t),(x,y),dp;
poly f=x+y+1;
string texf=texDrawTropical(tropicalCurve(f),list("",1));
texDrawBasic(texf);
