colinout - inner-outer factorization

### Calling Sequence

  `[Inn,X,Gbar]=colinout(G)`

### Parameters

- `G` : linear system (`syslin` list) `[A,B,C,D]`
- `Inn` : inner factor (`syslin` list)
- `Gbar` : outer factor (`syslin` list)
- `X` : row-compressor of `G` (`syslin` list)

### Description

Inner-outer factorization (and column compression) of (lxp) `G =[A,B,C,D]` with l<=p.

`G` is assumed to be fat (`l<=p` ) without zero on the imaginary axis and with a `D` matrix which is full row rank.

`G` must also be stable for having `Gbar` stable.

Dual of `rowinout` .
