# minimum(_:) Returns the double-precision minimum value of a vector. ``` static func minimum(_ vector: U) -> Double where U : AccelerateBuffer, U.Element == Double ``` ## Parameters `vector` The input vector. ## Return Value The minimum value of the vector. ## Discussion This function calculates the minimum value of the first `N` elements of input vector `A`, and writes the result to output scalar `C`. ![A diagram showing the operation of this function. There are three rows. The top row represents the input vector, A, with three boxes. The middle row represents the operation a box that contains the minimum function. The bottom row represents the output scalar value C as a box. The diagram has connecting lines from the input vector to the operation, and from the operation to the output scalar value.](images/com.apple.accelerate/media-4465974@2x.png) The following code shows an example of using this function: ```swift let a: [Double] = [-1.5, 2.25, 3.6, 0.2, -0.1, -4.3] let minimum = vDSP.minimum(a) print("minimum", minimum) // Prints "minimum -4.3". ``` --- Copyright © 2026 Apple Inc.
