# divide(_:_:result:)

Calculates the double-precision element-wise division of a scalar value and a vector.

## Declaration

```swift
static func divide<U, V>(_ scalar: Double, _ vector: U, result: inout V) where U : AccelerateBuffer, V : AccelerateMutableBuffer, U.Element == Double, V.Element == Double
```

## Parameters

- `scalar`: The input scalar value, A.
- `vector`: The input vector, B.
- `result`: The output vector, C.

## Discussion

Discussion This function calculates the element-wise division of scalar value A and vector B, and writes the result to vector C.  for (n = 0; n < N; ++n)     C[n] = A / B[n];

The following code shows an example of using this function:     let count = 5          let a: Double = 100     let b: [Double] = [1, 2, 3, 4, 5]          let c = [Double](unsafeUninitializedCapacity: count) {         buffer, initializedCount in                  vDSP.divide(a, b,                     result: &buffer)                  initializedCount = count     }          // Prints "[100.0, 50.0, 33.33, 25.0, 20.0]".     print(c)
