dear statalists

i have a cross-section dataset (1 year) of dyadic data; how can I get a correct variance-covariance matrix of estimates?

I organize data in a matrix; I should cluster for both row and column  simultaneously.....
eg.: (for firms a, b and c, number 1 indicate if the two firms have something in common):

  a  b  c
a    1  0
b 1     1
c 0  1
