You don't need to use the matrix or mata commands in Stata.

All you need is to save the information as variables in Stata and
-outsheet- it into a .out file.   I think you should outsheet the data
without the variable names, and then outsheet it again with only the
variable names and no data (drop if _n>0).  Send both files to your
friend and he/she would be able to read that data into Gauss without
much problem.

Dear Nick and others,

The TRUTH.... I need to send this matrix to someone who is using GAUSS....
that is why I wanted to just generate this matrix and send it across. This
matrix will then be used for simulations.

On the stata manual, i agree... unfortunately i do not have the manuals at
home (only in school) and so could not look it up toute suite today being a
Sunday. Anyway, I will look at them when i am in school tomorrow.

Thanks,

Gauri
