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.
