steadycos

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 ] ])

`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-4abs([x;u])`
`param(2)`	: scalar. Time t

Finds an equilibrium state of a general dynamical system described by a scicos diagram.
