Euler Angles

Exercises and case studies for a rigorous approach to risk- and portfolio-management. This booklet stems from the review sessions of the six-day ARPM bootcamp.Contents include:Advanced multivariate statistics; copula-marginal decompositionAnnualization/projection (FFT, cumulants,...

This toolbox can solve any of the 6 possible subproblems associated with an oblique spherical triangle, when only 3 of the 6 angles are known.The toolbox basically is an implementation of the set of tools developed in [Wertz, 2001], which aimed to fully automize the procedure and do away with the...

A few days ago I was in need of uniformly random points generation on the surface of sphere. I suddenly discovered that common parametrization with 2 angles is useless, it gathers too many points in the poles. At MathWorld you can find the complete demonstration, here the main lines:To pick a...
