Hey, I think the correct syntax would be matrix Q = beta_p .* Q_s Does this work? But I guess that your version shouldn't cause NaNs Artur Am 17.

Dear Fernando, I'd fixed the first line of your code and it worked just fine here on my Windows 7 PC (Gretl 2016c). matrix Q_s = {1, 1; 1, 1} # BEFORE: matrix Q_S = {1, 1; 1, 1} scalar beta_p = 0.9 matrix Q = beta_p * Q_s Using "*" or ".*" did not change the results. I will test on my OS/X computer tonight to check if is something specific to Windows. Um abraço, Henrique Andrade

In relation to the statements above, it's clear that beta_p * Q_S should produce a 2 x 2 matrix all of whose elements equal 0.9. But we don't know what beta_p * Q_s should produce, since we haven't seen a definition of Q_s.
