Description

Defined by taking fixed time steps from specified time reference and adding sampled times to array if they fall within specified bounding interval list.

Object Model

Public Properties

BoundingIntervalList	The bounding interval list.
IncludeIntervalEdges	Specify whether to include interval edges.
ReferenceTimeInstant	The reference time instant. Only applicable if the ReferenceType is set to time instant.
ReferenceType	Specify the time reference from which fixed sampling time steps are taken. Note: selecting Start/Stop of each Interval resets the time reference for each interval, whereas other types maintain single reference for entire array.
SamplingTimeStep	The sampling time step.

Example

Create and configure fixed step event array.
