Hope this is relevant for you:If you want for example to specify a ARMA model of order 1 / 1 you proceed as follows:spec = garchset('M',1,'R',1);[coeff,errors] = garchfit(spec,a2) %a2 contains the log-returns of the series you want to calibrate)[eSim,sSim,ySim] = garchsim(coeff,horizon,nPaths) % simulates the series nPaths times with a tick nuber specified with the horizonHope this helpsHeiko
