Singular Manual: piecewiseWeightOfPolygon

| #### D.15.2.10 piecewiseWeightOfPolygon Procedure from library `arnold.lib` (see arnold_lib). Usage: piecewiseWeightOfPolygon(NP); a list NP as given by @ref(newtonPolygon) Return: the piecewiseweight defined by the Newton polygon NP Example:
    LIB "arnold.lib";
    ring R=0,(x,y),ds;
    poly f = x^9+x^2*y^4+y^2*x^4+y^8+x^3*y^5+y^2*x^5;
    list NP = newtonPolygon(f);
    piecewiseWeightOfPolygon(NP);
