creating matrix of coefficient covariance values

hi-- I would like to create matrices of the coefficient covariance matrices generated by the code:

Code:

estat vce

I need to use these matrices in a standard error calculation, so they need to be in a usable matrix format that allows me to do matrix multiplication etc.
I have tried using:

Code:

matrix covmat = get(vce)

but this has not worked.

thank you
