executeSerialMergepublic MatrixObject executeSerialMerge() Description copied from class:ResultMergeMerge all given input matrices sequentially into the given output matrix. The required space in-memory is the size of the output matrix plus the size of one input matrix at a time.- Specified by:
- executeSerialMergein class- ResultMerge<MatrixObject>
- Returns:
- output (merged) matrix
 
 - 
executeParallelMergepublic MatrixObject executeParallelMerge(int par) Description copied from class:ResultMergeMerge all given input matrices in parallel into the given output matrix. The required space in-memory is the size of the output matrix plus the size of all input matrices.- Specified by:
- executeParallelMergein class- ResultMerge<MatrixObject>
- Parameters:
- par- degree of parallelism
- Returns:
- output (merged) matrix
