# vDSP_vsdiv

Calculates the single-precision element-wise division of a vector and a scalar value, using the specified stride.

```
extern void vDSP_vsdiv(const float *__A, vDSP_Stride __IA, const float *__B, float *__C, vDSP_Stride __IC, vDSP_Length __N);
```

## Parameters

`__A`

The input vector, `A`.

`__IA`

The distance between the elements in the input vector.

`__B`

The input scalar, `B`.

`__C`

The output vector, `C`.

`__IC`

The distance between the elements in the output vector.

`__N`

The number of elements that the function processes.

## Discussion

This function calculates the element-wise division of vector `A` and scalar value `B`, and writes the result to vector `C`.

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

![A diagram showing the operation of this function. There are three rows. The top row represents the input vector A with three boxes, and the scalar value B with one box. The middle row represents the operation as three boxes with division signs. The bottom row represents the output vector C as three boxes. The diagram has connecting lines from the input vectors to the operation, and from the operation to the output vector. ](images/com.apple.accelerate/media-4337205@2x.png)

The following code shows an example of using this function:

```swift
    let stride = 1
    let count = 5
    
    let a: [Float] = [1, 2, 3, 4, 5]
    let b: Float = 10
    
    let c = [Float](unsafeUninitializedCapacity: count) {
        buffer, initializedCount in
        
        vDSP_vsdiv(a, stride,
                   [b],
                   buffer.baseAddress!, stride,
                   vDSP_Length(count))
        
        initializedCount = count
    }
    
    // Prints "[0.1, 0.2, 0.3, 0.4, 0.5]".
    print(c)
```
