Vector-scalar real arithmetic functions

Overview

The vDSP library provides a suite of general-purpose, high-performance arithmetic functions that are alternatives to for loops and map when you apply operations on collections of floating-point values.

See Using vDSP for vector-based arithmetic for a summary of available operations.
