# ramp(in:count:) Returns a double-precision vector that contains monotonically incrementing or decrementing values within a range. ``` static func ramp(in range: ClosedRange, count: Int) -> [Float] ``` ## Parameters `range` The start and end values of the generated ramp. `count` The number of elements in the ramp. ## Discussion Use this function to generate and return a vector populated with ramped values. The following code generates a ramped vector with values in the range `0 ... 7`: ```swift let ramp = vDSP.ramp(in: Float(0) ... 7, count: 8) // Prints "[0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0]". print(ramp) ``` --- Copyright © 2026 Apple Inc.
