colcompr(8)

NAME
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)

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