lincos

lincos — linearizes a system described by a scicos diagram

Calling sequence

sys= lincos(scs_m [,x0,u0 [,param] ])

scs_m : a Scicos data structure

x0 : column vector. Continuous state around which linearization to be done (default 0)

u0 : column vector. Input around which linearization to be done (default 0)

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

sys : state-space linear model

Constructs by linearization a linear state-space model from a general dynamical system described by a scicos diagram.
