10 Model Advisor Checks
Check for calls to slDataTypeAndScale
Identify calls to the internal function slDataTypeAndScale.
Description
In some previous versions of Simulink, opening a model that had been saved in an earlier version triggers an automatic upgrade to code for data type handling. The automatic upgrade inserts calls to the internal function slDataTypeAndScale. Although Simulink continues to support some uses of the function, if you eliminate calls to it, you get cleaner and faster code.
Simulink does not support calls to slDataTypeAndScale when:
•The first argument is a Simulink.AliasType object.
•The first argument is a Simulink.NumericType object with property IsAlias set to true.
Running Check for calls to slDataTypeAndScale identifies calls to slDataTypeAndScale that are required or recommended for replacement. In most cases, running the check and following the recommended action removes the calls. You can ignore calls that remain. Run the check unless you are sure there are not calls to slDataTypeAndScale.

Tips
•Do not manually insert a call to slDataTypeAndScale into a model. The function was for internal use only.
•Running Check for calls to slDataTypeAndScale calls the Simulink function slRemoveDataTypeAndScale. Calling this function directly provides a wider range of conversion options. However, you very rarely need more conversion options.
