init(concatenating:alongAxis:)

Declaration

init<S>(concatenating shapedArrays: S, alongAxis: Int) where Scalar == S.Element.Scalar, S : Sequence, S.Element : MLShapedArrayProtocol

Parameters

• shapedArrays:

  A sequence of shaped arrays.

• alongAxis:

  A zero-based axis number the shaped arrays in multiArray merge along.

Discussion

All shaped arrays in the sequence must have the following:

• The same underlying data type

• The same number of dimensions

• The same size for each corresponding dimension, except for the concatenation axis

For example, this code concatenates two shaped arrays along their second dimension:

// A 2x3 shaped array.
// 0 1 2
// 5 6 7
let shapedArray1 = MLShapedArray<Int32>(scalars: [0, 1, 2, 5, 6, 7],
                                        shape: [2, 3])

// A 2x2 shaped array.
// 3 4
// 8 9
let shapedArray2 = MLShapedArray<Int32>(scalars: [3, 4, 8, 9],
                                        shape: [2, 2])

// A 2x5 shaped array.
// 0 1 2 3 4
// 5 6 7 8 9
let shapedArray3 = MLShapedArray(concatenating: [shapedArray1,shapedArray2],
                                 alongAxis: 1)
