Alexander Hans commented on MAHOUT-531:
---------------------------------------
Ted,
you say that for DenseMatrix I should assume that all values are non-zero.
Shouldn't that apply to DenseVector as well? Currently the iterateNonZero() of
DenseVector skips elements whose value is zero. With the implementation
contained in the latest patch we would introduce an inconsistency.
> MatrixWritable doesn't actually write/read anything

> The write() and readFields() methods of MatrixWritable write/read only the
> classname, they don't write/read actual data.
