Does anyone know of efficient software for the multiplication with an anti-triangular matrix? These are matrices whose triangular structures goes from the lower left corner to the upper right corner. Are there codes similar to the Level 3 BLAS routines for the multiplication of these matrices? They come up in light scattering computations in high dimensions.(adsbygoogle = window.adsbygoogle || []).push({});

Thanks.
