Subject [Hadoop Wiki] Trivial Update of "Matrix" by udanax

Dear Wiki user,

------------------------------------------------------------------------------
  
  The matrix package will be useful for Large-Scale Numeric Analysis and Data Mining which
need the computation system of the Inverse Matrix (e.g. linear regression, PCA, SVM, ...,
etc).
  
- Generally, The current shared-memory based parallel matrix solution provides a scalable
and high performance matrix operations, but, matrix resources can't be scalable. But, Using
Hbase's 2- dimensional Row and Column(Qualifier) space, we are able to store large sparse
matrix. Also, auto-partitioned sparsity sub-structure will be efficiently managed and serviced
by Hbase. Row or Column operations can be done in linear time and algorithms such as structured
Gaussian elimination or iterative methods run in O(~-the number of non-zero elements in the
matrix-~ / ~-number of mappers (processors/cores)-~) time on Map/Reduce.
