*My solution:*
open australia.gdt
var 4 lpus le lpau
loop i=1..3
    series uhat$i = $uhat[,$i])
endloop
YourMatrix <- corr uhat1 uhat2 uhat3

*Allin's solution:*
open australia.gdt
var 4 lpus le lpau
matrix MC = mcorr($uhat)
print MC

*Riccardo's solution:*
open australia.gdt
var 4 lpus le lpau -q
S = $sigma
s = sqrt(diag(S))
S = S ./ (s.*s')
print S

Conclusion: It's impossible to be more elegant than you, Allin and Riccardo!

Best,
Henrique

My solution:

endloop
YourMatrix <- corr uhat1 uhat2 uhat3

Allin's solution:

Riccardo's solution:
open australia.gdt
var 4 lpus le lpau -q
S = $sigma
s = sqrt(diag(S))
S = S ./ (s.*s')
print S

Dear Olle, I don't know if there is a command for this, but you can use a
small script:

open australia.gdt
var 4 lpus le lpau

loop i=1..3
   series uhat$i = $uhat[,$i])
endloop

YourMatrix <- corr uhat1 uhat2 uhat3

Or:

open australia.gdt
var 4 lpus le lpau
matrix MC = mcorr($uhat)
print MC

Or:

open australia.gdt

var 4 lpus le lpau -q
S = $sigma
s = sqrt(diag(S))
S = S ./ (s.*s')
print S
