Convert transfer function filter parameters to lattice filter form
[k,v] = tf2latc(b,a)
k = tf2latc(1,a)
[k,v] = tf2latc(1,a)
k = tf2latc(b)
k = tf2latc(b,'phase')
[k,v] = tf2latc(b,a) finds
the lattice parameters k and the ladder parameters v for
an IIR (ARMA) lattice-ladder filter, normalized by a(1).
Note that an error is generated if one or more of the lattice parameters
are exactly equal to 1.
k = tf2latc(1,a) finds the
lattice parameters k for an IIR
all-pole (AR) lattice filter.
[k,v] = tf2latc(1,a) returns
the scalar ladder coefficient at the correct position in vector v.
All other elements of v are zero.
k = tf2latc(b) finds the
lattice parameters k for an FIR (MA) lattice filter,
normalized by b(1).
k = tf2latc(b, specifies the type of FIR (MA) lattice filter, where 'phase')'phase' is
'max', for a maximum phase filter.
'min', for a minimum phase filter.
