>
> The RealMatrixImpl class has only the setSubMatrix method for updating matrix 
> elements.
> It would be useful to include methods to
> (i)  set the elements of one row of a matrix
> (ii) set the elements of one column of the matrix.
> Possible signatures are:
> setRow(int rowIndex, double[]      rowVector)
> setRow(int rowIndex, RealVector rowVector)
> setColumn(int columnIndex, double[]      columnVector)
> setColumn(int columnIndex, RealVector columnVector)
