# vDSP_zvconj

Calculates the complex conjugate of the values in a single-precision vector using the specified stride.

```
extern void vDSP_zvconj(const DSPSplitComplex *__A, vDSP_Stride __IA, const DSPSplitComplex *__C, vDSP_Stride __IC, vDSP_Length __N);
```

## Parameters

`__A`

Single-precision complex input vector

`__IA`

Stride for `A`

`__C`

Single-precision complex output vector

`__IC`

Stride for `C`

`__N`

The number of elements to process

## Discussion

Conjugates elements of vector `A`, leaving results in `C`.
