Rachel--
It's a safe bet that every function is built in (not interpreted
code).  It's an even safer bet that all the matrix functions are built
in--even the -matrix- subcommands are!

The references at http://mathworld.wolfram.com/CholeskyDecomposition.html
might tell you the relevant formulas...

though I sincerely doubt you need them.

I would like to see the code for several of Stata's matrix functions

are implemented.

-which- cholesky tells me it's not implemented as either an ado or
built-in function, so I assume I must be using the wrong name.

Can anyone help?

Thanks,
Rachel
