merge

public static MatrixBlock merge(MatrixBlock a,
                                MatrixBlock b,
                                boolean appendOnly,
                                boolean par,

Merge b into a, if possible otherwise

Parameters:

a - MatrixBlock a to merge into if possible

b - MatrixBlock b to take elements from

appendOnly - If the appending can be done into a sparse block without sorted indexes

par - If parallelism is allowed

deep - If the copy should be deep most common is true

Returns:

The merged MatrixBlock
