st: Re: out of space/memory error on Unix

[Kit Baum <baum@bc.edu>]

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.
