Re: [eigen] feature request: implement hybrid matrix class template

Yes, this allocates a static buffer for the matrix.

But is that stack allocated , like the blaze hybrid matrix ?

Hi Vincent,

Happy new year as well.

This feature is already implemented through the two last optional template parameters of the Matrix class (see http://eigen.tuxfamily.org/dox/group__TutorialMatrixClass.html).

If you want a matrix M with maximum size (6,4) for example, you can write

Matrix<double, Dynamic, Dynamic, 0, 6, 4> M;    // 0 specifies a column-major storage

Cheers,

Adrien

Hi,

Happy new year, In 2018, can hybrid matrix class template be implemented in Eigen? Hybrid matrix class template combines the flexibility of a dynamically sized matrix with the efficiency and performance of a fixed size matrix.

Thanks,

Vincent
