4.23.1 coneViaPoints
Syntax:
coneViaPoints( intmat HL )
coneViaPoints( intmat HL, intmat L )
coneViaPoints( intmat HL, intmat L, int flags )
Type:
- cone
Purpose:
- cone generated by half lines generated by the row vectors of HL
and (if stated) by lines generated by the row vectors of L;
flags may range between 0,..,3 defining an upper and lower bit
(0=0*2+0, 1=0*2+1, 2=1*2+0, 3=1*2+1),
if upper bit is 1, then program assumes that each row vector in HL
generates a ray of the cone,
if lower bit is 1, then program assumes that the span of the row
vectors of L is the lineality space of the cone,
if either bit is 0, then program computes the information itself.
