org.drip.spaces.big.SubMatrixSetExtractor
public class SubMatrixSetExtractor
extends java.lang.Object
SubMatrixSetExtractor contains the Functionality to extract the Set of the Sub-matrices contained inside of the given Matrix. It provides the following Functionality:
  • Compute the Aggregate Composite Value of the Supplied Matrix
  • Generate the List of all the sub-matrices contained within a specified Square Matrix starting from the given Row and Column
  • Compute the Maximum Composite Value of all the sub-matrices contained within a specified Square Matrix starting from the given Row and Column
  • Use the "Lean" Method to compute the Maximum Composite Value of all the sub-matrices contained within a specified Square Matrix starting from the given Row and Column
