exactly sure what might be the best strategy yet hence the question. It's
really interesting that LAPACK doesn't have this type of fast checks.

In Fortran LAPACK, if you have a special structured matrix, you usually
explicitly use packed storage and call the appropriate function type on it.
It's only when you go to a system that only has a generic, unstructured
dense matrix data type that it makes sense to do those kinds of checks.
