Select a registered computation engine

Selects the registered engine used when a specification is computed. Because the engine determines the numerical evidence, applying engine() to a computed result updates its stored specification and recomputes through the same path as other evidence-changing verbs.

Usage

engine(spec, name)

Arguments

spec

A simtab_spec or simtab_result.

name

A single registered engine name. See list_engines().

Value

A modified simtab_spec, or a recomputed simtab_result.

register_engine(), evaluate()
