latcfilt
Lattice and lattice-ladder filter implementation.
[f,g] = latcfilt(k,x) [f,g] = latcfilt(k,v,x) [f,g] = latcfilt(k,1,x)
[f,g] = latcfilt(k,x)
filters x with the FIR lattice coefficients in vector k. f is the forward lattice filter result and g is the backward filter result.
If k and x are vectors, the result is a (signal) vector.
Matrix arguments are permitted under the following rules:
x is a matrix and k is a vector, each column of x is processed through the lattice filter specified by k.
x is a vector and k is a matrix, each column of k is used to filter x, and a signal matrix is returned.
x and k are both matrices with the same number of columns, then the i-th column of k is used to filter the i-th column of x. A signal matrix is returned.
[f,g] = latcfilt(k,v,x)
filters x with the IIR lattice coefficients k and ladder coefficients v. k and v must be vectors, while x may be a signal matrix.
[f,g] = latcfilt(k,1,x)
filters x with the IIR all-pole lattice specified by k. k and x may be vectors or matrices according to the rules given for the FIR lattice.
Filter data with a recursive (IIR) or nonrecursive (FIR) filter. |
