r26605 - /trunk/test_suite/unit_tests/_lib/_geometry/test_vectors.py -- November 17, 2014 - 17:29

Author: bugman
Date: Mon Nov 17 17:29:14 2014
New Revision: 26605

URL: http://svn.gna.org/viewcvs/relax?rev=26605&view=rev
Log:
Added 6 unit tests for the lib.geometry.vectors.vector_angle_acos() function.

These are similar to those of the vector_angle_normal() function but unsigned 
angles are checked
for.
