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.

Math operations such as sin, cos, min, max,
and abs do not work with complex data in C charts.
However, you can use MATLAB^{®} functions for these operations.

When you define the initial value for data that is complex,
use only a real value. See Set Properties in the Description Pane for instructions
on setting an initial value in the Data properties dialog box.

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.
