# threshold(_:to:with:result:)

Calculates the elements of the supplied single-precision vector after applying a specified thresholding rule.

## Declaration

```swift
static func threshold<U, V>(_ vector: U, to lowerBound: Float, with rule: vDSP.ThresholdRule<Float>, result: inout V) where U : AccelerateBuffer, V : AccelerateMutableBuffer, U.Element == Float, V.Element == Float
```
