# sumOfMagnitudes(_:)

Returns the single-precision vector sum of magnitudes.

## Declaration

```swift
static func sumOfMagnitudes<U>(_ vector: U) -> Float where U : AccelerateBuffer, U.Element == Float
```

## Parameters

- `vector`: The vector to sum.

## Discussion

Discussion This function calculates and returns the sum of the magnitudes of the elements of a supplied vector. The following is an example of using sumOfMagnitudes(_:): let a: [Float] = [-1.5, 2.25, 3.6,                   0.2, -0.1, -4.3]

let sumOfMagnitudes = vDSP.sumOfMagnitudes(a)

// Prints "sum of magnitudes 11.9500" print(String(format: "sum of magnitudes %.4f", sumOfMagnitudes))
