I'm wondering if anyone knows about the size limit for converting
SparseArrays to their Normal form. For example, if you try
you'll get back the error message SparseArray::ntb. Does anyone know
exactly what the maximum size is? Is there a way to change this? It
seems the documentation for some of these error messages is only half
written (shame, Wolfram!)
On a similar note, there seems to be a bug associated to large array
sizes. For example, try
which produces SparseArray::dims, complaining that the dimensions aren't
a list of postive integers...
More generally, does anyone have a definitive (or even partial) list of
functions which know how to operate directly on SparseArrays, without
having to resort to their Normal forms?
