irf store the results for each step matrix not found

[Wen-Hung Hsu]

Hello,

After estimating VAR model, I would love to get the cumulative impulse return functions and the values for each step until 15.

var vwretd sdvol_1 r_1, lags(1/5)
irf create myirf, set(myirfs, replace) step(15)
irf table cirf, impulse(sdvol_1) response(sdvol_1) individual step(15)

and the results are like

+--------------------------------------------+
|        |    (1)         (1)         (1)    |
|  step  |   cirf       Lower       Upper    |
|--------+-----------------------------------|
|0       | 1           1           1         |
|1       | 1.09572     1.09146     1.09997   |
|2       | 1.0778      1.07148     1.08411   |
|3       | 1.04753     1.03972     1.05535   |
|4       | 1.03347     1.02448     1.04247   |
|5       | 1.03666     1.02664     1.04667   |
|6       | 1.03824     1.02806     1.04843   |
|7       | 1.03829     1.02829     1.04829   |
|8       | 1.03769     1.02783     1.04755   |
|9       | 1.03732     1.02749     1.04714   |
|10      | 1.03722     1.02737     1.04706   |
|11      | 1.03723     1.02738     1.04708   |
|12      | 1.03726     1.02741     1.04711   |
|13      | 1.03726     1.02742     1.0471    |
|14      | 1.03725     1.02741     1.04709   |
|15      | 1.03724     1.0274      1.04709   |
+--------------------------------------------+

Now I would love to to store the values for each step by

irf describe myirf
mat list r(myirfs_order)

with the error

matrix r(myirfs_order) not found

I am not quite sure if I use the correct name of matrix to get the values for each step according to the impulse and response valuables. The reference link is here:

Can someone help to to store the values according to the impulse and response valuables?
