[Gretl-users] isnull for matrices
Hi,
I encountered that a matrix that 'is null' cannot be filtered by
'isnull':
<hanls>
matrix test = {1,0,3;1,1,100}
eval isnull(test)
matrix seek = selifr(test,test[,1].=1)
matrix seek = selifr(seek,seek[,2].=2)
eval seek
eval isnull(seek)
# and also not working
eval ok(test)
eval ok(seek)
<hanls>
Best
Leon
