# DSPComplex

A structure that represents a single-precision complex value.

## Declaration

```swift
struct DSPComplex
```

## Mentioned in

Controlling vDSP operations with stride Performing Fourier transforms on interleaved-complex data

## Overview

Overview Complex data are stored as ordered pairs of floating-point numbers. Because they are stored as ordered pairs, complex vectors require address strides that are multiples of two.

## Topics

### Initializers

- [init()](accelerate/dspcomplex/init().md)
- [init(real:imag:)](accelerate/dspcomplex/init(real:imag:).md)

### Instance Properties

- [imag](accelerate/dspcomplex/imag.md)
- [real](accelerate/dspcomplex/real.md)
