Closes #2739.
With reference to the issue above, I added a new
ZonotopeMD
type, a representation of zonotopes of orderk
in normal form. This type has 2 constructors for buildingZonotopeMD
from either a[M D]
generator matrix or fromM
andd
separately.The specialized
cartesian_product
returns aZonotopeMD
in normal form. TheM'
block in the resulting generatorG' = [M' D']
, has 50% of 0 entries so it is stored as a sparse matrix for efficiency
