colcompr - column compression of polynomial matrix

Calling Sequence

[Y,rk,ac]=colcompr(A);

Parameters

• A : polynomial matrix
• Y : square polynomial matrix (right unimodular basis)
• rk : normal rank of A
• Ac : Ac=A*Y, polynomial matrix

Description

column compression of polynomial matrix A (compression to the left)

Examples

s=poly(0,'s');
p=[s;s*(s+1)^2;2*s^2+s^3];
[Y,rk,ac]=colcompr(p*p');
