Decimation

Option to apply decimation factor for logged output, state, and time data

Model Configuration Pane: Data Import/Export

Description

Specify the decimation factor, n, such that every nth data point is logged for outputs, states, and time.

Settings

1 (default) | positive integer greater than zero

• With the default value 1, all data points are logged for outputs, states, and time.

• The specified value must be a positive integer greater than zero.

• The value of this parameter is not tunable during simulation.

Tips

• For some models and simulation conditions, logging can produce large amounts of data. Use this parameter to reduce the number of samples logged when a reduced effective sample rate is sufficient.

• You can also use the Limit data points to last parameter to reduce the number of sample values saved for output, state, and time logging.

• For more information about configuring which data points are logged for different logging techniques, see Specify Signal Values to Log.
