Scicos function

steadycos - Finds an equilibrium state of a system described by a scicos diagram

### Calling Sequence

  `[X,U,Y,XP]=steadycos(scs_m,X,U,Y,Indx,Indu,Indy [,Indxp [,param ] ])`

### Parameters

- `scs_m` : a Scicos data structure
- `X` : column vector. Continuous state. Can be set to [] if zero.
- `U` : column vector. Input. Can be set to [] if zero.
- `Y` : column vector. Output. Can be set to [] if zero.
- `Indx` :vector, index of entries of X that are not fixed. If all can vary, set to 1:$
- `Indu` : vector, index of entries of U that are not fixed. If all can vary, set to 1:$
- `Indy` :vector, index of entries of Y that are not fixed. If all can vary, set to 1:$
- `Indxp` :vector, index of entries of XP (derivative of X) that need not be zero. If all can vary, set to `1:$`. Default [].
- `param` : list with two elements (default `list(1.d-6,0)`)
- `param(1)` : scalar. Perturbation level for linearization; the following variation is used `del([x;u])_i = param(1)+param(1)*1d-4*abs([x;u])`
- `param(2)` : scalar. Time t
