d2arrayIndices

inline fun <T : Any> Multik.d2arrayIndices(    sizeD1: Int,     sizeD2: Int,     init: (i: Int, j: Int) -> T): D2Array<T>
Content copied to clipboard

Creates a new 2-dimensions array of the specified (sizeD1, sizeD2) shape, where each element is calculated by calling the specified init function.

The function init is called for each array element sequentially starting from the first one. It should return the value for an array element given its indices.
