Save Runtime Data from Simulation

Save simulation data to MATLAB® workspace; log signals; export signal, time, output, and state data

Simulation data can include any combination of signal, time, output, state, and data store logging data.

Exporting simulation data involves saving signal values to the MATLAB workspace or to a MAT-file during simulation for later retrieval and postprocessing. Exporting data is also known as data logging or saving simulation data.

For information on the different approaches for exporting signal data, see Export Simulation Data.

Blocks

Outport Create output port for subsystem or external output
