but if one does whole-array updates, there isn't much to be gained by avoiding intermediate copies, is there? whether you fill a new memory area, or overwrite an old one, you still have to loop through the whole thing, writing and reading.
I would gain a 20% reduction in memory use, which could come out to a few gigabytes for large problems. That's worth some degree of effort. Actually, it'd be a bit less than 20%, but for large problems it would approach 20%. -- David Roundy Department of Physics Oregon State University
