Option to log only last n data points for outputs, states, and time
Model Configuration Pane: Data Import/Export
Description
Specify whether to log all values or log only the last n data points for outputs, states, and time.
Settings
off (default) | on
off
States and outputs are logged for the entire simulation.
on
Only the last n output, state, and time values are logged. Specify the number of data points to save in the text box. By default, the number of data points to save when you select Limit data points to last is 1000.
Tips
- For some models and simulation conditions, logging can produce large amounts of data. Use this parameter to limit the number of values logged when you only need to analyze data from the end of the simulation.
- Setting the value of this parameter directly impacts memory allocation. When you specify this parameter, the software allocates memory upfront based on the specified value, not on the actual time steps generated during the simulation. For this reason, the Limit data points to last parameter is not recommended when logging an indeterminate number of time steps.
- You can also apply a decimation factor to reduce the number of values logged for outputs, states, and time. For more information, see Decimation.
- For more information about configuring which data points are logged for different logging techniques, see Specify Signal Values to Log.
