Annotation for code generation
annotation"(" InlineAfterIndexReduction "=" ( false | true ) ")
Has only an effect within a function declaration. If true, the model developer proposes to inline the function after the function is differentiated for index reduction, and before any other symbolic transformations are performed.
InlineAfterIndexReduction = true is for example used in Modelica.Mechanics.Rotational.Sources.Move to define that an input signal is the derivative of another input signal.
