Rotation Matrices¶

Definition of rotation matrices¶

rotmat.R() ... 3D rotation matrix for rotation about a coordinate axis

Conversion Routines¶

rotmat.convert() ... Convert a rotation matrix to the corresponding quaternion
rotmat.sequence() ... Calculation of Euler, Fick/aeronautic, Helmholtz angles

Symbolic matrices¶

rotmat.R_s() ... symbolix matrix for rotation about a coordinate axis

For example, you can e.g. generate a Fick-matrix, with

R_Fick = R_s(2, ‘theta’) * R_s(1, ‘phi’) * R_s(0, ‘psi’)
