Convert lattice filter parameters to transfer function form
[num,den] = latc2tf(k,v)
[num,den] = latc2tf(k,'iiroption')
num = latc2tf(k,'firoption')
[num,den] = latc2tf(k,v) finds the transfer function numerator num and denominator den from the IIR lattice coefficients k and ladder coefficients v.
[num,den] = latc2tf(k,'iiroption') produces an IIR filter transfer function according to the value of the string 'iiroption':
'allpole': Produces an all-pole filter transfer function from the associated all-pole IIR lattice filter coefficients k.
'allpass': Produces an allpass filter transfer function from the associated allpass IIR lattice filter coefficients k.
num = latc2tf(k,'firoption') produces an FIR filter according to the value of the string 'firoption':
'min': Produces a minimum-phase FIR filter numerator from the associated minimum-phase FIR lattice filter coefficients k.
'max': Produces a maximum-phase FIR filter numerator from the associated maximum-phase FIR lattice filter coefficients k.
'FIR': Produces a general FIR filter numerator from the lattice filter coefficients k (default, if you leave off the string altogether).
