getOutputIndex

Get index of an output element of an operating point specification

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

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

customized trimming of Simulink models, getOutputIndex lets you obtain the index of

an output specification based on the corresponding block path.

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 = getOutputIndex(op,block)

index = getOutputIndex(op,block,port)

index = getOutputIndex(op,block,port,element)

Description

index = getOutputIndex(op,block) returns the index of the output specification

that corresponds to block in the Outputs property of operating point specification op.

index = getOutputIndex(op,block,port) returns the index of the output

specification that corresponds to the trim output constraint added to the specified output

port of the specified block.

Use this syntax when the Outputs property of op contains trim output constraints for

more than one signal originating from the same block.

index = getOutputIndex(op,block,port,element) returns the index of the

specified element within an output specification for an output with multiple elements.
