Command in octave

for lagnumber=1:number_of_lags
tempmat=lagmatrix(x,lagnumber)
Z=[Z tempmat(number_of_lags+1:end,:)];
end
I have used this command in Matlab and its working. but when I run this command in Octave. it gave me error in lag matrix. what is problem?/

@sebastien Can you confirm that lagmatrix is not available under Octave?

Indeed, lagmatrix is not available under Octave.

for lagnumber=1:number_of_lags
tempmat=lagmatrix(x,lagnumber)
Z=[Z tempmat(number_of_lags+1:end,:)];
end

You need to dowload it from one of the publicly available toolboxes.
