ORTHOGONAL MULTI-WAVELETS FROM MATRIX FACTORIZATION Xiao, Hongying;
Accuracy of the scaling function is very crucial in wavelet theory, or correspondingly, in the study of wavelet filter banks. We are mainly interested in vector-valued filter banks having matrix factorization and indicate how to choose block central symmetric matrices to construct multi-wavelets with suitable accuracy.
