With any transfer between programs you are going to loose 
some reproducability of your analysis. In this case, where 
you want to manipulate a matrix, there is no good reason 
for moving away from Stata. So, tell us what you want to 
do, and we will tell you how to do it in Stata.

Having said that, the matrices e(b) and e(V) are stored in
working memory, so if you want to access them in another
program you will have to store them. You can use programs
like : Michael Blasnik's and Ben Jann's -mat2txt- for that.
To install that type in Stata -ssc install mat2txt-.

Hope this helps,
Maarten
