To compute the steady-state operating point, call `findop`

using
either of the following syntaxes:

[X,U] = findop(sys,'steady',InputLevel,OutputLevel)
[X,U] = findop(sys,spec)

To compute the states, `X`

, and the input, `U`

,
of the steady-state operating point, `findop`

minimizes
the norm of the error *e*(*t*) = *y*(*t*)-*f*(*x*(*t*), *u*(*t*)),
where:

You can specify the search algorithm and search options using
the `findopOptions`

option set.

The algorithm uses the following independent variables for minimization:

Because `idnlarx`

model states are delayed
samples of the input and output variables, the state values are the
constant values of the corresponding steady-state inputs and outputs.
