D.15.27.1 transWithPrecision
Procedure from library transformation.lib (see transformation_lib).
- Usage:
- transWithPrecision(f,T,d); f poly, T 1xn matrix, where n is the number of variables of the basering, d int
- Return:
- the image of f under the transformation defined by T up to degree d
Example:
| | LIB "transformation.lib";
ring R=0,(x,y,z),ds;
poly f = 2*x^2+5*x*y+7*x^7;
matrix T[1][3]=x+2*y+y^2,y+x^2*y,z+y^2+z^2*x;
transWithPrecision(f,T,7);
==> 2x2+13xy+18y2+4xy2+13y3+5x3y+10x2y2+2y4+5x2y3+7x7+98x6y+588x5y2+1960x4y3+\
