Decimation
Description
Specify the decimation factor, n, such that every nth data point is logged for outputs and states.
Category: Data Import/Export
Settings
Default:
1
With the default value,
1
, all data points are saved for logged outputs and states.The specified value must be a positive integer greater than zero.
The value of this parameter is not tunable.
Simulink® outputs data at the specified number of data points. For example, specifying
2
saves every other data point, while specifying10
saves one in ten data points.
Tips
For some models and simulation conditions, logging can produce large amounts of data. Use this parameter to limit the number of samples saved 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 and states logging.
For more information about configuring which data points are logged for different logging techniques, see Specify Signal Values to Log.
