Return sample time information for a block


ts = Simulink.Block.getSampleTimes(block)

Input Arguments


Full name or handle of a Simulink block

Output Arguments


The Simulink.Block.getSampleTimes function returns ts, a 1-by-n array of Simulink.SampleTime objects associated with the specified model. Here n is the number of sample times associated with the model. The format of the returns is:

1xn Simulink.SampleTime
Package: Simulink

value: [1x2 double] Description: [char string] ColorRGBValue: [1x3 double] Annotation: [char string] OwnerBlock: [char string] ComponentSampleTimes: [1x2 struct]

  • value — A two-element array of doubles that contains the sample time period and offset. For multirate, the value is empty since Simulink assign any sample time period and offset.

  • Description — A character vector or string that describes the sample time type

  • ColorRGBValue — A 1x3 array of doubles that contains the red, green and blue (RGB) values of the sample time color

  • Annotation — A character vector or string that represents the annotation of a specific sample time (for example 'D1')

  • OwnerBlock — For asynchronous, controllable, IRT, discrete export-functions, and variable sample times, a character vector or string containing the full path to the block that controls the sample time. For all other types of sample times, an empty character vector or string.

  • ComponentSampleTimes — A structure array of elements of the same type as Simulink.Block.getSampleTimes if the sample time is an asynchronous union or if the sample time is multirate and the component sample times are available.


ts = Simulink.Block.getSampleTimes(block) performs an update diagram and then returns the sample times of the block connected to the input argument mdl/signal. This method performs an update diagram to ensure that the sample time information returned is up-to-date. If the model is already in the compiled state via a call to the model API, then an update diagram is not necessary.

Using this method allows you to access all information in the Timing Legend programmatically.
