object Companion(source)

Factories for sparse vectors.

Functions

of

@JvmStatic

fun of(size: Int, indices: IntArray, values: DoubleArray): SparseVector(source)

Build a sparse vector, sorting by index and summing duplicates. Copies its inputs.

wrap

@JvmStatic

fun wrap(size: Int, indices: IntArray, values: DoubleArray): SparseVector(source)

Wrap existing arrays without copying, taking ownership; indices must already be strictly ascending and in range. The structural indices cannot be recovered for mutation afterwards.
