linearInterpolate(values:atIndices:)

Returns the double-precision linearly interpolated values of a vector at the specified indices.

Declaration

static func linearInterpolate<T, U>(values: T, atIndices indices: U) -> [Double] where T : AccelerateBuffer, U : AccelerateBuffer, T.Element == Double, U.Element == Double

Parameters

  • values:

    The values to interpolate.

  • indices:

    The indices to the output vector.

Return Value

A vector that contains the linearly interpolated values.

Discussion

The following code creates a five-element vector from two values using linear interpolation. The last index in indices determines the length of the operation result.

let values: [Double] = [0, 100]
let indices: [Double] = [0, 4]

let result = vDSP.linearInterpolate(values: values,
                                    atIndices: indices)

// Prints "[0.0, 25.0, 50.0, 75.0, 100.0]".
print(result)
