Loop unrolling threshold

Specify minimum array size width for generating for loops

Model Configuration Pane: Code Generation / Optimization


The Loop unrolling threshold specifies the minimum array size width for which a for loop is generated.


If you want to use this parameter for specifying the minimum array size width for parallel for-loops, Embedded Coder® is required.


5 (default)

Specify the array size at which the code generator begins to use a for loop instead of separate assignment statements to assign values.

When there are perfectly nested loops, the code generator uses a for loop if the product of the loop counts for loops in the perfect loop nest is greater than or equal to the threshold.
