Review request for mahout.
Repository: mahout
Description
-------
matrixLike() in our sparse vectors should return a SparseMatrix not return
a SparseRowMatrix as its mainly used for outer products which produce many zero
rows
MatrixWritable should preserve the type of sparse matrix (currently it
always deserializes as SparseRowMatrix)
provide an optimized assign for addition in SparseMatrix
