The Wolfram Language provides a core set of functions for performing block-diagram reduction and various model manipulations. Building on the Wolfram Language's unique symbolic architecture, models and their connections are elegantly represented and manipulated as symbolic expressions.

Model Connections

SystemsModelSeriesConnect — connects two models in series

SystemsModelParallelConnect — connects two models in parallel

SystemsModelStateFeedbackConnect — connects two models using state feedback

SystemsModelFeedbackConnect — connects two models using feedback

SystemsModelMerge — connects several models by merging inputs, state, and outputs

SystemsConnectionsModel — a model of subsystems and unevaluated interconnections

Model Manipulations

SystemsModelDelete — deletes a subsystem

SystemsModelExtract — extracts a subsystem
