Data Store Examples
Overview
The following examples illustrate techniques for defining and
accessing data stores. See Ordering Data Store Access for techniques that control data
store access over time, such as ensuring that a given data store is
always written before it is read. See Using Data Store Diagnostics for techniques you can use to
help detect and correct potential data store errors without needing
to run any simulations.

Local Data Store Example
The following model illustrates creation and access of a local
data store, which is visible only in a model or particular subsystem.
This model uses a data store to permit subsystem A to signal
that its output is invalid. If subsystem A's output is invalid, the
model uses the output of subsystem B.

Global Data Store Example
The following model replaces the subsystems of the previous
example with functionally identical submodels to illustrate use of
a global data store to share data in a model reference hierarchy.
In this example, the top model uses a signal object in the MATLAB workspace
to define the error data store. This is necessary because data stores
are visible across model boundaries only if they are defined by signal
objects in the MATLAB workspace.
