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!).
