Direct Known Subclasses:

XMicroBlock, YMicroBlock

public abstract class MatrixMicroBlock
extends MicroBlock

This class extends to MicroBlock class to provided extra functionality common to the XMicroBlocks and YMicroBlocks that are both based on matrix data structrues. An array is used as the under;lying data structure and the print and multiply methods are implemented at this level,

Specified by:

initialiseDataStructures in class MicroBlock

multiplyRow

protected BigRational multiplyRow(int index)
                           throws UndefinedMultiplyException

Throws:

UndefinedMultiplyException

multiply

public void multiply(BigRational[] result)
              throws BTFMatrixErrorException

Description copied from class: ComponentBlock

Carries out the appropriate matrix multiplication operation for the block
