Name
rowcompr — row compression of polynomial matrix
Calling Sequence
[X,rk,Ac]=rowcompr(A)
Parameters
- A
polynomial matrix
- Y
square polynomial matrix (left unimodular basis)
- rk
normal rank of A
- Ac
: Ac=X*A, polynomial matrix
Description
row compression of polynomial matrix A.
X is a left polynomial unimodular basis which row compressed
thee rows of A. rk is the normal rank of A.
Warning: elimination of "small" terms (use with care!).
