@Override
public Vector clone() {
 MatrixVectorView r = (MatrixVectorView) super.clone();
 r.matrix = matrix.clone();
 r.row = row;
 r.column = column;
 r.rowStride = rowStride;
 r.columnStride = columnStride;
 return r;
}

@Override
public Matrix clone() {
 MatrixView clone = (MatrixView) super.clone();
 clone.matrix = matrix.clone();
 clone.offset = offset.clone();
 return clone;
}
