Does anyone know how can I get mata matrix in stata
matrix. I give one example here.
mata:
A = st_matrix("iotaN1")
B = st_matrix("iotaN2")
C = st_matrix("iotaN3")
D = blockdiag(A, blockdiag(B,C))
end
When I try "mat dir", I don't see matrix D.
I want to get back the matrix D on stata to make my
matrix calculation, but I do not know how to make it.
You need to use the command
mata describe
from the mata : prompt to see what matrices mata has created. And you
can return matrices from mata to Stata using:
st_matrix("newmat",D)
which you can then see from within Stata (after using -end- to quit
mata) with
mat dir
which should show not only your iotaN1 iotaN2 iotaN3, but also newmat.
There is a good summary of this on page 503 of the Mata manual (on
st_global, Remarks).
