D.6.9.15 stripHNE
Procedure from library hnoether.lib (see hnoether_lib).
- Usage:
- stripHNE(L); L list
- Assume:
- L is the output of
develop(f) , or of
extdevelop(develop(f),n) , or (one entry of) the list
hne in the ring created by hnexpansion(f[,"ess"]) .
- Return:
- list in the same format as L, but all polynomials L[4], resp.
L[i][4], are set to zero.
- Note:
- The purpose of this procedure is to remove huge amounts of data
no longer needed. It is useful, if one or more of the polynomials
in L consume much memory. It is still possible to compute invariants,
parametrizations etc. with the stripped HNE(s), but it is not possible
to use
extdevelop with them.
Example:
See also:
develop;
extdevelop;
