absolute(_:)

Returns the absolute value of each element in the supplied double-precision vector.

Declaration

static func absolute<U>(_ vector: U) -> [Double] where U : AccelerateBuffer, U.Element == Double

Parameters

  • vector:

    The source vector.

Discussion

For example, the following code calculates the absolute values of the elements of an array:

    let values: [Double] = [-1, 2, -3, 4, -5, 6, -7, 8]
    
    let absoluteValues = vDSP.absolute(values)
    
    // Prints "[1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0]".
    print(absoluteValues)
