# fill(_:with:)

Populates a single-precision vector with a specified scalar value.

## Declaration

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

## Parameters

- `vector`: The vector to populate with the specified value.
- `value`: The value to populate.

## Discussion

Discussion This function populates a vector with a specified scalar value. The following code shows how to set each element of vector c to pi: let a = Float.pi

var c = [Float](repeating: .nan,                 count: 10)

vDSP.fill(&c,           with: a)

// Prints "[3.1415925, 3.1415925, 3.1415925, //          3.1415925, 3.1415925, 3.1415925, //          3.1415925, 3.1415925, 3.1415925, //          3.1415925]" print(c)
