# init(scalars:shape:) Initialize an ndArray with a copy of some sequence of scalars, stored in the ndArray in row-major order. ``` init(scalars: some Sequence, shape: [Int]) where Scalar : BitwiseCopyable ``` ## Parameters `scalars` A sequence of scalars to be copied into the new ndArray. Note that `Scalar` must be a type that corresponds to a scalar type found on the [`NDArray.ScalarType`](/documentation/CoreAI/NDArray/ScalarType-swift.enum) enum. `shape` The shape of the new ndArray. The ndArray will be stored in row-major order and the scalars will be assigned in row-major order. ## Discussion This utility will construct an ndArray with a copy of the contents of some sequence. For example to make an int32 ndArray with increasing values: ```swift var ndArray = NDArray(scalars: (0..<4) as Range, shape: [2, 2]) // The resulting NDArray has contents: [[0, 1], [2, 3]] ``` --- Copyright © 2026 Apple Inc.
