I wonder if this Mata error message is the equivalent of the regular
Stata error message "op.sys. refuses to provide memory." Since such a
matrix would have 34.5 million cells, it would require ~275 megabytes.
Although this is far below any limit Mata would impose (Mata allows 2+
billion rows and 2+ billion columns) your machine may not be willing to
satisfy the memory request.

Thanks to Kit for both suggestions -tmpdir-, which I've now
installed, and
the Stata FAQ, which I should have found. I've managed to change the
tmpdir from /tmp to something in my user, for which the limit is
only the
physical hard disk space, but I'm not sure I've solved the problem. I
still get the same error message - "3900 unable to allocate real
<tmp>[287115,120]". I wonder if mentioning that the "problem" is
almost
certainly due to a Mata matrix (287115X120) is worth anything.
