Abstract

It is given an efficient complete parametrization of wavelet matrices of rank mm, genus g+1g+1, and degree gg, which are naturally identified with corresponding polynomial paraunitary matrix-functions. The parametrization depends on Wiener-Hopf factorization of unitary matrix-functions with constant determinant given in the unit circle. This method allows us to construct in real time the coefficients of wavelet matrices from the above class.
