Get index of an input element of an operating point specification

The `Inputs`

property of an operating point specification is
an array that contains trimming specifications for each model input. When defining a
mapping function for customized trimming of Simulink^{®} models, you can use `getInputIndex`

to obtain the index
of an input 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.
