Class LibMatrixBincell

java.lang.Object

org.apache.sysds.runtime.matrix.data.LibMatrixBincell

public class LibMatrixBincell
extends Object

Library for binary cellwise operations (incl arithmetic, relational, etc). Currently, we don't have dedicated support for the individual operations but for categories of operations and combinations of dense/sparse and MM/MV. Safe/unsafe refer to sparse-safe and sparse-unsafe operations.
