Converting a State or Subchart to an Atomic Subchart

To convert a state or subchart to an atomic subchart, right-click the object in your chart and select Make Contents > Atomic Subcharted.

After you convert a state or subchart to an atomic subchart, local data appears as data store memory in the atomic subchart.

An atomic subchart looks opaque like a regular subchart but includes the label (Atomic) in the upper-left corner. If you use a linked atomic subchart from a library, the label (Link) appears in the upper-left corner.

For example, the following model contains a chart, Air Controller, that uses an atomic subchart:

In the Air Controller chart, PowerOn is an atomic subchart, but PowerOff is a regular subchart:

When an Atomic Subchart Is a Library Link

To convert a linked atomic subchart back to a state or subchart:

1. Right-click the atomic subchart and select Link Options > Disable Link.

2. Follow the steps in When an Atomic Subchart Is Not a Library Link.

When an Atomic Subchart Is Not a Library Link

To convert an atomic subchart back to...	Follow these steps...
A state	Right-click the atomic subchart in your chart and clear the Make Contents > Atomic Subcharted check box. Right-click the object again and clear the Make Contents > Subcharted check box. You might need to rearrange graphical objects in your chart after performing this step.
A regular subchart	Right-click the atomic subchart in your chart and clear the Make Contents > Atomic Subcharted check box.

Restrictions for Converting an Atomic Subchart to a State or Subchart

In the following cases, converting an atomic subchart to a state or subchart does not work:

• Your atomic subchart uses a MATLAB function and contains a nontrivial mapping of variables. A mapping is nontrivial when the variable in the subchart does not map to another variable of the same name in the container chart.

• A parameter in the atomic subchart maps to something other than a single variable. For example, the following mappings for a parameter named data1 prevent conversion of an atomic subchart to a state or subchart:

  • data2 + 3

  • data2.3

  • data2(3)

  • 3
