Singular Manual: texDrawNewtonSubdivision

| #### D.13.3.23 texDrawNewtonSubdivision Procedure from library `tropical.lib` (see tropical_lib). Usage: texDrawNewtonSubdivision(graph[,#]); graph list, # optional list Assume: graph is the output of tropicalCurve Return: string, the texdraw code of the Newton subdivision of the tropical plane curve encoded by graph Note: - the list # may contain optional arguments, of which only one will be considered, namely the first entry of type 'poly'; this entry should be a rational number which specifies the scaling factor to be used; if it is missing, the factor will be computed; the list # may as well be empty - note that lattice points in the Newton subdivision which are black correspond to markings of the marked subdivision, while lattice points in grey are not marked Example:
    LIB "tropical.lib";
    ring r=(0,t),(x,y),dp;
    poly f=x+y+x2y+xy2+1/t*xy;
    list graph=tropicalCurve(f);
    // compute the texdraw code of the Newton subdivision of the tropical curve
    texDrawNewtonSubdivision(graph);
