getStateIndex

Get index of a state element of an operating point specification or operating point

The States property of an operating point specification is an array that contains

trimming specifications for each model state. When defining a mapping function for

customized trimming of Simulink models, getStateIndex lets you obtain the index of a

state specification based on the corresponding block path or state name.

When trimming Simulink models using optimization-based search, some applications

require additional flexibility in defining the optimization search parameters. For such

systems, you can specify custom constraints and a custom objective function. For complex

models, you can define a mapping that selects a subset of the model states, inputs, and

outputs to pass to the custom constraint and objective functions. For more information,

see “Compute Operating Points Using Custom Constraints and Objective Functions” on

page 1-78.

Syntax

index = getStateIndex(op,name)

index = getStateIndex(op,name,element)

Description

index = getStateIndex(op,name) returns the index of the state specification that

corresponds to name in the States property of operating point specification op.

index = getStateIndex(op,name,element) returns the index of the specified

element within a state specification for a block with multiple states.
