Unlike MATLAB or GAUSS, Mata functions can return any amount of stuff (variables, locals, globals, matrices, scalars) using the st_* commands. See help m4_stata for details. Your bhat could be returned with st_matrix; the easiest way IMHO to return a variable is to create it in Stata and use st_view to modify it in Mata.

ssc type hprescott.ado

gives an example of the latter.

how can i tell mata to return 2 results
res1=bhat and res2=uhat. res1 and res2 are for use in the rest of my programme.
Ideally I want some thing like this:
{b,u}=myreg() as can i code in gauss for exemple
