Implementations of the composite parameterization for the unitary group U(d) and special unitary group SU(d) of arbitrary dimension d. The present mathematica files also yield the associated (normalized) Haar measures on U(d) and SU(d), as well as the exact parameter ranges.
Possible applications: Optimization problems and group integrals over U(d) and SU(d).
For details on the parameterization and the corresponding Haar measure see the references: http://arxiv.org/abs/1004.5252 and http://arxiv.org/abs/1103.3408
