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!).
