- Using Hbase's Row,Column(Qualifier) two dimensional space, we are able to store large sparse matrix. Also using iterative algorithms like conjugate gradient method on a parallel processing platform like MapReduce,
+ Using Hbase's Row,Column(Qualifier) two dimensional space, we are able to store large sparse matrix.
+ [[BR]]Also using iterative algorithms like conjugate gradient method on a parallel processing platform like MapReduce,
we should be able to implement '''High Performance''' and '''World's Largest''' Matrix Computations.
The HbaseLINA will be added as sub-shell in [:Hbase/HbaseShell:Hbase Shell].

+ === Applications ===
+
+ * Scientific simulation and modeling
+ * Matrix-vector/matrix-matrix multiply
+ * Soving linear systems
+ * Information retrieval
+ * Sorting
+ * Finding eigenvalues and eigenvectors
+ * Computer graphics and computational geometry
+ * Matrix multiply
+ * computing matrix determinate
