Check Stateflow charts for unary operators

Check ID: mathworks.hism.hisf_0211

Identify unary operators in Stateflow^® charts.

This check identifies the unary minus operators on unsigned data types in Stateflow charts.

Available with Simulink^® Check™.

This check requires a Stateflow license.

Condition	Recommended Action
The Stateflow chart consists of a unary minus operator on unsigned data types.	Explicitly modify the unary operator on unsigned data types. For more information, see Unary Operations and Actions (Stateflow).

Does not run on library models.
Analyzes content of library linked blocks. By default, the input parameter Follow links is set to on.
Analyzes content in masked subsystems. By default, the input parameter Look under masks is set to all.
Except for Shift and Divide operations, this check does not flag expressions with bitwise and arithmetic operators.
