# add(_:_:result:)

Calculates the single-precision element-wise sum of two vectors.

## Declaration

```swift
static func add<T, U, V>(_ vectorA: T, _ vectorB: U, result: inout V) where T : AccelerateBuffer, U : AccelerateBuffer, V : AccelerateMutableBuffer, T.Element == Float, U.Element == Float, V.Element == Float
```

## Parameters

- `vectorA`: The first input vector, A.
- `vectorB`: The second input vector, B.
- `result`: The output vector, C.

## Discussion

Discussion This function calculates the sums of the first N elements of input vectors A and B, and writes the result to output vector C.  for (n = 0; n < N; ++n)     C[n] = A[n] + B[n];

The following code shows an example of using this function:     let count = 5

let a: [Float] = [ 1,  2,  3,  4,  5]     let b: [Float] = [10, 20, 30, 40, 50]

let c = [Float](unsafeUninitializedCapacity: count) {         buffer, initializedCount in                  vDSP.add(a, b,                  result: &buffer)                  initializedCount = count     }         // Prints "[11.0, 22.0, 33.0, 44.0, 55.0]".     print(c)
