D.5.2.45 classpoly

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:

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) );
