Hi, look what the package <<Geometry`Rotations` can do for you. The function RotationMatrix3D[] will accept Euler angles.

Unfortunately it takes ages for mathematica (5.2) to calculate these. Does any one know what the best way is for storing ~4000 3 by 3 matrices. Also does mathematica have an algorithm for turning matrices in to Euler angles as it might be better to store them that way. > > Thanks > John >
