Allow symbolic dimension specification

Option to propagate symbolic dimensions throughout model

Model Configuration Pane: Diagnostics


The Allow symbolic dimension specification parameter specifies whether Simulink® software:

  • Propagates symbols used to specify symbolic dimensions throughout the model

  • Preserves the symbols in the generated code


on (default) | off

Simulink propagates symbolic dimensions throughout the model and preserves these symbols in the generated code when using Embedded Coder®.


The software propagates the numeric values associated with the symbolic specification throughout the model but the symbols do not appear in the generated code.
