M-XRAY calculates all the model metrics required to determine the complexity of a Simulink or TargetLink model.

Metric	Description
Halstead metrics	Weighted complexity metrics adapted for Simulink and TargetLink models
Global complexity	Measured complexity of a dedicated subsystem, chart, or state (children included)
Local complexity	Measured complexity of a subsystem, chart, or state (without children)
Hierarchy level	Hierarchy level in the model where the subsystem, chart, or state is located
Blocks	Number of Simulink blocks on each subsystem level
Interface width	Number of Inports and Outports for each subsystem including buses
Chart complexity	Measured chart complexity
States	Number of Stateflow states and substates
Actions	Number of action parts in chart
Events	Number of events used in chart
EnDuEx	Number of entry, during, and exit actions used in a chart
Conditions	Number of transition conditions used in a chart
Transitions	Number of transitions used in a chart
