C charts do not support complex number notation (a
+ bi), where a and b are
real numbers. Therefore, you cannot use complex number notation in
state actions, transition conditions and actions, or any statements
in C charts.
In the Data properties dialog box, do not enter any values in
the Minimum or Maximum field
when you define complex data. If you enter a value in either field,
an error message appears when you try to simulate your model.
