Assignment Operations

The following assignment operations are supported in Stateflow action language.

Example
Description

a = expression
Simple assignment

a := expression
Used primarily with fixed-point numbers. See Assignment (=, :=) Operations for a detailed description.

a += expression

Equivalent to a = a + expression

a -= expression

Equivalent to a = a - expression

a *= expression

Equivalent to a = a * expression

a /= expression

Equivalent to a = a / expression

Example	Description
`a = expression`	Simple assignment
`a := expression`	Used primarily with fixed-point numbers. See Assignment (=, :=) Operations for a detailed description.
`a += expression`	Equivalent to `a = a + expression`
`a -= expression`	Equivalent to `a = a - expression`
`a *= expression`	Equivalent to `a = a * expression`
`a /= expression`	Equivalent to `a = a / expression`

The following assignment operations are supported in Stateflow action language when Enable C-bit operations is selected in the properties dialog for the chart. See Specifying Chart Properties.

Example
Description

a |= expression
Equivalent to a = a | expression (bit operation). See operation a | b in Binary and Bitwise Operations.

a &= expression
Equivalent to a = a & expression (bit operation). See operation a & b in Binary and Bitwise Operations.

a ^= expression
Equivalent to a = a ^ expression (bit operation). See operation a ^ b in Binary and Bitwise Operations.

Example	Description
`a \|= expression`	Equivalent to `a = a \| expression` (bit operation). See operation `a \| b` in Binary and Bitwise Operations.
`a &= expression`	Equivalent to `a = a & expression` (bit operation). See operation `a & b` in Binary and Bitwise Operations.
`a ^= expression`	Equivalent to `a = a ^ expression` (bit operation). See operation `a ^ b` in Binary and Bitwise Operations.
