DefaultGenericNDArray

open class DefaultGenericNDArray<T> :NDArray<T>

An (unoptimized) implementation of NDArray in pure Kotlin, for portability between the different platforms koma supports.

Parameters

shape - A vararg specifying the size of each dimension, e.g. a 3D array with size 4x6x8 would pass in 4,6,8)

init - A function that takes a location in the new array and returns its initial value.
