Log Dataset data to file

Log simulation data saved using theDatasetformat to a MAT-file.

Category:Data Import/Export

Default:'off'

On

Enables logging data saved using theDatasetformat to a MAT-file.

Log simulation data to a MAT-file when you know prior to simulation that you want to save the results in a file.

Specify the path and file name for the MAT-file.

Off

Disables logging simulation data to a MAT-file.

To use theLog Dataset data to fileoption, select one or more of these types of data to log:
- States
- Final states
- Signal logging
- Output
- Data stores
- Stateflow^®states and data
If you are logging states or output data, set theFormatparameter toDataset.
If you select theFinal statesparameter, clear theSave final operating pointparameter.
When the data in the MAT-file fits into memory, use theloadfunction to access the data.
When the data in the MAT-file is too large to fit into memory, access the data in the MAT-file usingSimulink.SimulationData.DatasetRefandmatlab.io.datastore.SimulationDatastoreobjects.
Except for parallel simulations, Simulink^®overwrites the contents of the MAT-file during each simulation unless you change the name of the file between simulations. For details, seeSave Logged Data from Successive Simulations.
