D.15.4.45 classpoly

Procedure from library chern.lib (see chern_lib).

Usage:
classpoly(l, t); l list of polynomials, t polynomial

Return:
polynomial

Purpose:
computes the polynomial in t with coefficients being the entries of l

Note:

Example:
 
LIB "chern.lib";
ring r=0, (c(1..5), t), ds;
list l=c(1..5);
// get the polynomial c(1)*t + c(2)*t^2 + ... + c(5)*t^5
print( classpoly(l, t) );
==> c(1)*t+c(2)*t^2+c(3)*t^3+c(4)*t^4+c(5)*t^5
