Hello,

I am using Eigen with Visual Studio 2010 and I cannot execute my code because it gives me the error C2244: 'Eigen::SparseMatrixBase<Derived>::operator *' : unable to match function definition to an existing declaration. This error comes from the file SparseDenseProduct.h.
Even if I do not use any product of a sparse matrix by a dense matrix, it still gives this error. If I put in comment the last lines of the file SparseDenseProduct.h, I have no problem using any other function of Eigen.

Can you please help me ?

Please, use latest 3.2 version: https://bitbucket.org/eigen/eigen/get/3.2.zip
