D.12.4.3 chinrestp

Procedure from library hyperel.lib (see hyperel_lib).

Usage:
chinrestp(b,moduli); moduli, b, moduli=list of polynomials

Return:
poly x, s.t. x= b[i] mod moduli[i]

Note:
chinese remainder theorem for polynomials

Example:
 
LIB "hyperel.lib";
ring R=7,x,dp;
list b=3x-4, -3x2+1, 1, 4;
list moduli=(x-2)^2, (x-5)^3, x-1, x-6;
chinrestp(b,moduli);
==> -x6-3x5-x4+2x3-2x2+3x+3
