D.2.5.6 showrecursive
Procedure from library inout.lib (see inout_lib).
- Usage:
- showrecursive(id,p[,ord]); id any object of basering, p= product of
variables and ord=string (any allowed ordstr)
- Display:
- display 'id' in a recursive format as a polynomial in the variables
occurring in p with coefficients in the remaining variables. This is
done by mapping to a ring with parameters [and ordering 'ord',
if a 3rd argument is present (default: ord="dp")] and applying
procedure 'show'
- Return:
- no return value
Example:
| | LIB "inout.lib";
ring r=2,(a,b,c,d,x,y),ds;
poly f=y+ax2+bx3+cx2y2+dxy3;
showrecursive(f,x);
==> // poly, 4 monomial(s)
==> (b)*x3+(a+cy2)*x2+(dy3)*x+(y)
showrecursive(f,xy,"lp");
==> // poly, 5 monomial(s)
==> (b)*x3+(c)*x2y2+(a)*x2+(d)*xy3+y
