Method Details

combine

public static MatrixBlock combine(Map<MatrixIndexes,MatrixBlock> m,
 Map<Integer,List<IDictionary>> d,
 int k)

Combine the map of index matrix blocks into a single MatrixBlock. The intension is that the combining is able to resolve differences in the different MatrixBlocks allocation.

Parameters:

m - The map of Index to MatrixBLocks

d - A map of the dictionaries contained in the compression scheme

k - The parallelization degree allowed for this operation

Returns:

The combined matrix.

combine

public static MatrixBlock combine(Map<MatrixIndexes,MatrixBlock> m,
 Map<Integer,List<IDictionary>> d,
 int rlen,
 int clen,
 int blen,
 int k)

Alternative read, when dimensions are known.

Parameters:

m - The sub matrix blocks

d - The sub dictionaries

rlen - n rows

clen - n cols

blen - block size

k - Parallelization degree

Returns:

The combined matrixBlock
