Developed a data-structure for representing the 2-dimensional block matrices and perform basic matrix operations.
1. buildTwoDBlockMatrix() :- takes a reference to a stream from which the matrix is read and a reference to the newly created object is returned.
2. toString() :- Returns the String representation of a TwoDBlockMatrix object.
3. transpose() :- If the calling object contains a 2-dimensional matrix of size m x n . The method returns the new transposed 2-dimensional matrix of size n x m . The original matrix remains same.
4. multiply() :- This method takes another matrix object of type TwoDBlockMatrix. The method should return the product of two input matrix. If the two matrices are not compatible, it throws expception.
5. getSubBlock() :- This method returns the sub-block of the TwoDBlockMatrix object that belongs to the slice with input rows and columns. It throws an exception when there is no underlying sub-block in the specified range.
6. inverse() :- The method returns a new TwoDBlockMatrix object containing the inverse of the given matrix. In case the inverse matrix does not exist, function raises an exception rather than returning anything.
