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');
p*p'*Y
