colinout

colinout — inner-outer factorization

Calling sequence

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

`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)

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.
