|  |  D.4.16.2 PrimdecA Procedure from librarymprimdec.lib(see  mprimdec_lib).
 
Example:Usage:
PrimdecA (N[, i]); module N, int i
Return:
list l
a (not necessarily minimal) primary decomposition of N
computed by a generalized version of the algorithm of Shimoyama/Yokoyama,
 if i!=0 is given, the factorizing Groebner is used to compute the
isolated primes
