Get index of an input element of an operating point specification or operating point

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, `getInputIndex`

lets
you 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.

`index = getInputIndex(op,block)`

`index = getInputIndex(op,block,element)`
