Web1 Answer. Sorted by: 5. yes, this normalization will produce a uniform distribution in S U ( N), however, it might be more efficient to generate directly random matrices with unit determinant (you'll need one fewer parameter and no need to calculate the determinant), as explained in Composite parameterization and Haar measure for all unitary ... WebMay 4, 2015 · On closest unitary matrix. In this question ‖ A ‖ p is the normalized p -th Schatten norm which is defined to be ( E i λ i p) 1 / p, where λ i are singular values of matrix A.
