Map Root Inport Signal Data
To import, visualize, and map signal and bus data to root-level input ports, use the Root
Inport Mapper tool or the
getRootInportMap function. At the top level of a
model or referenced model, root-level input ports include:
Root-level input ports import data from the MATLAB® workspace based on the value of the Configuration Parameters > Data Import/Export > Input parameter.
Root-level inport mapping imports signal data in a way that meets most modeling requirements and maintains model flexibility. You can:
Test your model with signals from the workspace and use your model as a referenced model in a larger context without any modification.
Update the Input parameter based on the signal data you import and map to root-level inports.
Visually inspect signal data without loading all the data into MATLAB memory.
To determine whether another data import technique meets your specific modeling requirements (such as the amount of data or the storage location) better, see Comparison of Signal Loading Techniques.
You can use the
to create a
custom object to map signals to root-level input ports and
to create a custom map mode. For more
information, see Create and Use Custom Map Modes.
Import and Mapping Workflow
Map the imported signal data. For example, you can map the signal data by block path or signal name.
Simulate the model using the mapped data. After associating a scenario with the model, you can generate scripts for simulation with scenarios to perform batch simulations.
Optionally, save the current Root Inport Mapper scenario for future reference or to share with other people.
To extend the Root Inport Mapper tool map modes, you can create a custom mapping file function to map data to root-level inports.
View and Inspect Signal Data
After you import signal or bus data, you can view and inspect signal data using tools such as:
