indexOfMinimum(_:)

Returns the maximum value and corresponding index in a single-precision vector.

Declaration

static func indexOfMinimum<U>(_ vector: U) -> (UInt, Float) where U : AccelerateBuffer, U.Element == Float

Parameters

  • vector:

    The input vector.

Return Value

A tuple that contains the minimum value and corresponding index.

Discussion

This function calculates the minimum value and its corresponding index of the first N elements of the input vector and writes the results to the output scalar parameters, C and I, respectively.

The following code shows an example of using this function:

let a: [Float] = [-1.5, 2.25, 3.6,
                  0.2, -0.1, -4.3]

let indexOfMinimum = vDSP.indexOfMinimum(a)
print("indexOfMinimum", indexOfMinimum) // Prints "indexOfMinimum (5, -4.3)".
