Unused data, events, messages, and functions
Diagnostic action to take when unused data, events, messages, and functions in a chart are detected
Model Configuration Pane: Diagnostics
Description
The Unused data, events, messages, and functions parameter specifies the diagnostic action to take when Stateflow® detects unused data, events, messages, or functions in a chart. Removing unused data, events, messages, and functions can minimize the size of your model.
This diagnostic does not detect input events or MATLAB® function input and output data. Additionally, this diagnostic does not detect unused data for Stateflow charts that include Simulink® functions, Simulink based states, or atomic subcharts.
Settings
