smat parameter in impulse function generates zeros in matrix

[fboralli]

The smat parameter sometimes creates a matrix with a column full of zeroes in it. in the table, the real data is shown.

The code below reproduces this problem.

Code: Select all

wfcreate q 2000 2015 series a1=nrnd series a2=nrnd series a3=nrnd var v.LS 1 2 a1 a2 a3 v.impulse(16,t,smat=tt) a1 a2 @ a3

The table shown from the impulse and tt matrix should be equal, but they are not.
Screenshot attached.
