Basically I already have arrays: Values, InnerIndices, OuterStarts.
How to construct SparseMatrix from them?
http://eigen.tuxfamily.org/dox-devel/classEigen_1_1MappedSparseMatrix.html
The constructor seems not to be doxumented but it's basically
MappedSparseMatrix<Scalar, Eigen::ColMajor, Index>(Index rows, Index cols, Index nnz, Index* outerIndexPtr, Index* innerIndexPtr, Scalar* valuePtr)
Where Scalar is your scalar type and Index your index type.
