# vDSP_zvdivD

Divides two complex double-precision vectors.

```
extern void vDSP_zvdivD(const DSPDoubleSplitComplex *__B, vDSP_Stride __IB, const DSPDoubleSplitComplex *__A, vDSP_Stride __IA, const DSPDoubleSplitComplex *__C, vDSP_Stride __IC, vDSP_Length __N);
```

## Parameters

`__B`

Double-precision complex input vector. Note that `B` comes before `A`!

`__IB`

Stride for `B`.

`__A`

Double-precision complex input vector.

`__IA`

Stride for `A`.

`__C`

Double-precision complex output vector.

`__IC`

Stride for `C`.

`__N`

The number of elements to process.

## Discussion

This function divides the first `N` elements of `A` by corresponding elements of `B`, leaving the result in `C`.

The operation is:

```swift
for (n = 0; n < N; ++n)
    C[n] = A[n] / B[n];
```
