*Subject*: angles from rotation matrix*From*: Marc Schellens <m_schellens(at)hotmail.com>*Date*: Tue, 10 Jul 2001 20:16:21 +0900*Newsgroups*: comp.lang.idl-pvwave*Organization*: RIKEN*Xref*: news.doit.wisc.edu comp.lang.idl-pvwave:25605

Hello everybody! Is there a function in IDL to get the rotation angles from a given rotation matrix (in order first X than Y than Z (or arbitrary order))? Another problem I have is to find the rotation matrix to rotate two pointsets (Xi and Xii) so that the distance betweent the corresponding points of the set is minimized. I have a algorithm using SVDC, but wonder if IDL provides also another solution for this. thanks, marc
