Built-in functions: at_init function

at_init function


Returns the value the argument had when first used, i.e., on model reset or when the submodel instance containing this equation was created.

at_init(X) creates an implicit intermediate result, which has the same dimensions as its argument. So if this result is implicitly replicated elsewhere in the equation, the same value will be used each time. See makearray for behaviour in explicit replication.

Input: Any data type

Result: Same type as input
