Operations on Complex Data in Stateflow Action Language

Binary Operations Unary Operations and Actions Assignment Operations

Binary Operations

These binary operations work with complex operands in the following order of precedence (1 = highest, 3 = lowest). For operations with equal precedence, they evaluate in order from left to right.

Example	Precedence	Description
a * b	1	Multiplication
a + b	2	Addition
a - b	2	Subtraction
a == b	3	Comparison, equality
a != b	3	Comparison, inequality

Stateflow action language does not support division of complex operands because this operation requires a numerically stable implementation, especially when the base type of the complex data is fixed-point.

To perform complex division, use a MATLAB function, which provides a numerically accurate and stable result. For details, see Performing Complex Division with a MATLAB Function.

Unary Operations and Actions

These unary operations and actions work with complex operands.

Example	Description
~a	Unary minus
!a	Logical NOT
a++	Increment
a--	Decrement

Assignment Operations

These assignment operations work with complex operands.

Example	Description
a = expression	Simple assignment
a += expression	Equivalent to a = a + expression
a -= expression	Equivalent to a = a - expression
a *= expression	Equivalent to a = a * expression
