7.7.7.0. lp2ivId
Procedure from library fpadim.lib (see fpadim_lib).

Usage:
lp2ivId(G); G an ideal

Return:
list

Purpose:
Converting an ideal into an list of intmats,
the corresponding intvecs forming the rows.
For the encoding of the variables see the overview.

Assume:
- basering has to be a Letterplace ring

Example:
 
LIB "fpadim.lib";
ring r = 0,(x,y,z),dp;
def R = makeLetterplaceRing(5); // constructs a Letterplace ring
setring R; // sets basering to Letterplace ring
poly p = x(1)*x(2)*z(3); poly q = y(1)*y(2)*x(3)*x(4);
poly w = z(1)*y(2)*x(3)*z(4);
// p,q,w are some polynomials we want to transform into their
// intvec representation
ideal G = p,q,w;
// define the ideal containing p,q and w
lp2ivId(G); // and return the list of intmats for this ideal
==> [1]:
==>    1,1,3 
==> [2]:
==>    2,2,1,1,
==>    3,2,1,3
