Parentheses level

Specify parenthesization style for generated code.

Settings

Default: Nominal (Optimize for readability)

Minimum (Rely on C/C++ operators for precedence)

Inserts parentheses only where required by ANSI^®[1] C or C++, or needed to override default precedence. For example:

isZero = var == 0;
if (isZero == 1 && (value < 3.7 ||value > 9.27)) {
   /* code */
   }

Nominal (Optimize for readability)

Inserts parentheses in a way that compromises between readability and visual complexity. The exact definition can change between releases.

Maximum (Specify precedence with parentheses)

Includes parentheses everywhere needed to specify meaning without relying on operator precedence. Code generated with this setting conforms to MISRA^®[2] requirements. For example:

isZero = (var == 0);
if ((isZero == 1) && ((value < 3.7) || (value > 9.27))) {
   /* code */
   }

Preserve operand order in expression

Specify whether to preserve order of operands in expressions.

Settings

Default: off

On

Preserves the expression order specified in the model. Select this option to increase readability of the code or for code traceability purposes.

A*(B+C)

Off

Optimizes efficiency of code for nonoptimized compilers by reordering commutable operands to make expressions left-recursive. For example:

(B+C)*A

Preserve condition expression in if statement

Specify whether to preserve empty primary condition expressions in if statements.

Settings

Default: off

On

Preserves empty primary condition expressions in if statements, such as the following, to increase the readability of the code or for code traceability purposes.

if expression1
else
       statements2;
end

Off

Optimizes empty primary condition expressions in if statements by negating them. For example, consider the following if statement:

if expression1
else
       statements2;
end

By default, the code generator negates this statement as follows:

if ~expression1
        statements2;
end
