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,' produces
an IIR filter transfer function according to the value of iiroption')'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, produces
an FIR filter according to the value of 'firoption')'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 (this
is equivalent to not specifying 'iiroption' or 'firoption').
