# clear(_:) Populates a single-precision vector with zeros. ``` static func clear(_ vector: inout V) where V : AccelerateMutableBuffer, V.Element == Float ``` ## Parameters `vector` The vector to populate with zeros. ## 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: ```swift 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) ``` --- Copyright © 2026 Apple Inc.
