This section describes the C and Swift APIs for performing common routines on a single vector in vDSP. These functions perform tasks such as finding the absolute value of a vector, compressing the values of a vector, or converting between single and double precision vectors.
This document describes the vDSP portion of the Accelerate framework. The vDSP header provides a number of functions related to digital signal processing, including:
Vector and matrix arithmetic
Convolution, correlation, and window generation
For an overview that describes how to use these routines, read vDSP Programming Guide.
