# indexOfMinimum(_:)

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

## Declaration

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

## Parameters

- `vector`: The input vector.

## Return Value

Return Value A tuple that contains the minimum value and corresponding index.

## Discussion

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 vDSP_maxvi: let a: [Double] = [-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)".
