Optimize reductions

Single instruction, multiple data (SIMD) code for reduction operation loops

Since R2022a

Model Configuration Pane: Code Generation / Optimization

Description

The Optimize reductions parameter instructs the code generator to generate single instruction, multiple data (SIMD) code for reduction operation loops. A reduction is an operation that reduces a set of elements, such as an array, to a single value using an associative binary operator. For example, calculating the sum of the elements in an array is a reduction operation that uses the addition operator.

Dependencies

To use this parameter, you must set Instruction set extensions to a valid instruction set.
