Well, (4 x 10^4)^2 is a very large number of bytes, and I'm not surprised that your computer is not happy with that.

The matsize refers to the maximum number of rows and/or columns. Max for Intercooled is 800, which will allow for up to an 800 x 800. Can't have a 1676 x 1676 in Intercooled,l but you could in Stata/SE. Setting a matsize of 1700 in Stata/SE requires 23.269 Mb on my machine.

I can get away with set matsize of 10000 (which requires slightly over 800 Mb of memory), but then I have a Macintosh, and OS X knows how to use virtual memory efficiently...
