# add(multiplication:multiplication:result:)

Calculates the double-precision element-wise product of a vector and a vector, added to a second product of a vector and a vector.

## Declaration

```swift
static func add<R, S, T, U, V>(multiplication multiplicationAB: (a: R, b: S), multiplication multiplicationCD: (c: T, d: U), result: inout V) where R : AccelerateBuffer, S : AccelerateBuffer, T : AccelerateBuffer, U : AccelerateBuffer, V : AccelerateMutableBuffer, R.Element == Double, S.Element == Double, T.Element == Double, U.Element == Double, V.Element == Double
```
