Prepare Model Inputs and Outputs

Define external interfaces for input data and control signals, define output signals for viewing and recording simulation results

You can load signal data that you create in MATLAB^® or a spreadsheet or that you save during simulation. The kind of signal data you want to load impacts your choice of signal loading techniques.

For an overview of how to use MATLAB data in Simulink^® models, save simulation data, and log signals for analysis, watch Loading and Logging Data (4 min, 9 sec) and see Provide Signal Data for Simulation.

Attaching Input Data to External Inputs via Custom Input Mappings

Create a custom mapping function for the Root Inport Mapper tool. The Root Inport Mapper tool associates MAT-file data with a specific input port, based on one of these criteria.

Create Harness-Free Models with MAT File Input Data

Map MAT file data to the root-level input ports, which creates a harness-free model. Using root-level input ports can speed up simulation time. In the example, you convert a model with a Signal Editor input block to a harness-free model with root-level input ports. The harness-free model uses the data from the Signal Editor block MAT file.
