Binary coefficient wise operators can also mix sparse and dense expressions: Some binary coefficient-wise operators can also mix sparse and dense expressions:
\code \code
sm2 = sm1.cwiseProduct(dm1); sm2 = sm1.cwiseProduct(dm1);
dm2 = sm1 + dm1; dm1 += sm1;
\endcode \endcode
However, it is not yet possible to add a sparse and a dense matrix as in <tt>dm2 = sm1 + dm1</tt>.
Please write this as the equivalent <tt>dm2 = dm1; dm2 += sm1</tt> (we plan to lift this restriction
in the next release of %Eigen).
