A recursive parametrization of unitary matrices

Jarlskog, Cecilia LU (2005) In Journal of Mathematical Physics 46(10).
Abstract
A simple recursive scheme for parametrization of n-by-n unitary matrices is presented. The n-by-n matrix is expressed as a product containing the (n-1)-by-(n-1) matrix and a unitary matrix that contains the additional parameters needed to go from n-1 to n. The procedure is repeated to obtain recursion formulas for n-by-n unitary matrices.
