I tried some time ago to fit a diagonal error variance which was a smooth
function of time. Even after specifying the OWN structure with a diagonal
sparse inverse I had size problems which I could not understand unless the
matrix is treated as dense.

There seems to be a max size to the order of OWN structures. Does
anybody know what it is?

With the structure specified in sparse format, is it feasible to create
a diagonal OWN structure of order approx 10000?
