Recommended Settings Summary for Model Configuration Parameters - MATLAB & Simulink (original) (raw)
The following table summarizes the impact of each configuration parameter on debugging, traceability, efficiency, and safety considerations, and indicates the factory default configuration settings for the GRT and ERT targets, unless otherwise specified.
For parameters that are available only when an ERT target is specified, see Recommended Settings Summary for Model Configuration Parameters (Embedded Coder).
For additional details, click the links in the Configuration Parameter column.
