st: matrix decomposition

Subject   st: matrix decomposition

Dear all,

I want to get Stata to decompose a variance covariance (pos definite)
matrix, say V, into A*A', where A is not triangular as in the cholesky
decomposition (by the command cholesky(V)), but has other linear
restrictions e.g. zeros in different places. Anyone have any tips/examples
of how to program/command this?

Many thanks for any help,
