Lattice Structure for Paraunitary Linear-Phase Filter Babks with Accuracy
Paraunitary Linear-phase Accuracy
font style='font-size:12px;'>
2007/12/12
Multivariate filter banks with a polyphase matrix built by matrix factorization (lattice structure) were proposed to obtain orthonormal wavelet basis. On the basis of that, we propose a general method...
High-Accuracy P-Stable Methods with MinimalPhase-Lag for $y''=f(t,y)$

In this paper, we develop a one-parameter family of P-stable
sixth-order and eighth-order two-step methods with minimal phase-lag
errors for numerical integration of second order periodic initial va...
