Hi,

I was wondering if it is possible to somehow use some external storage
in blas expressions. What I imagine is a kind of matrix/vector proxy
that takes a pointer to the data and maybe a layout description. What
would be important to me is that the data is not copied. It is ok that
ownership is fragile, I would only use this temporarily to feed data
into expressions, not to store the data anywhere.

It looks to me like it should be possible to build such proxies, but
honestly I got lost in the machine trying to figure out exactly how...

Best
