7.7.6.0. ivKDim
Procedure from library fpadim.lib (see fpadim_lib).

Usage:
ivKDim(L,n[,degbound]); L a list of intmats,
n an integer, degbound an optional integer

Return:
int, the K-dimension of A/<L>

Purpose:
Computing the K-dimension of A/<L>

Assume:
- basering is a Letterplace ring.
- all rows of each intmat correspond to a Letterplace monomial
for the encoding of the variables see the overview
- if you specify a different degree bound degbound,
degbound <= attrib(basering,uptodeg) should hold.

Note:
- If degbound is set, a degree bound will be added. By default there
is no degree bound.
- n is the number of variables.
- If the K-dimension is known to be infinite, a degree bound is needed
