# clear(_:)

Populates a single-precision vector with zeros.

## Declaration

```swift
static func clear<V>(_ vector: inout V) where V : AccelerateMutableBuffer, V.Element == Float
```

## Parameters

- `vector`: The vector to populate with zeros.

## Discussion

Discussion This function populates a vector with zeros. The following code shows how to clear the array c, setting the value of each element to zero: var c = [Float](repeating: .nan,                 count: 10)

vDSP.clear(&c)

// Prints "[0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]" print(c)
