BigDenseMatrix

final class BigDenseMatrix extends AnyRef

Off-heap implementation of a Dense Matrix, matrix size is only limited by the amount of the available memory and the matrix dimension cannot exceed Integer.MAX_VALUE (this is consistent with XGBoost API restrictions on maximum length of a response).
