st: saving and loading matrices

[Oleksandr Shepotylo <shepotil@econ.umd.edu>]

Hi ,

Is there a way to save and load matrices in text  format?
Suppose I run Stata  and  want to use matrix A in another program X.
So, I want to save A in csv or txt  form. Then I do some manipulations 
with A and want to load A back in Stata while keeping all my data unchanged.

Thanks,
Oleksandr Shepotylo.
