initopspec

Initialize operating point specification values

Syntax

opnew=initopspec(opspec,oppoint)

opnew=initopspec(opspec,x,u)

opnew=initopspec(opspec,xstruct,u)

Description

opnew=initopspec(opspec,oppoint) initializes the operating point specification

object, opspec, with the values contained in the operating point object, oppoint. The

function returns a new operating point specification object, opnew. Create opspec with

the function operspec. Create oppoint with the function operpoint or findop.

opnew=initopspec(opspec,x,u) initializes the operating point specification object,

opspec, with the values contained in the state vector, x, and the input vector, u. The

function returns a new operating point specification object, opnew. Create opspec with

the function operspec. You can use the function getxu to create x and u with the

correct ordering.

opnew=initopspec(opspec,xstruct,u) initializes the operating point specification

object, opspec, with the values contained in the state structure, xstruct, and the input

vector, u. The function returns a new operating point specification object, opnew. Create

opspec with the function operspec. You can use the function getstatestruct or

getxu to create xstruct and the function getxu to create u with the correct ordering.

Alternatively, you can save xstruct to the MATLAB workspace after a simulation of the

model. See the Simulink documentation for more information on these structures.

Examples

Create an operating point using findop by simulating the magball model and extracting

the operating point after 20 time units.
