# crv_bounds¶

Forces the Cartesian rotation vector norm, $$\|\vec{\psi}\|$$, to be in the range $$[-\pi,\pi]$$, i.e. determines the rotation axis orientation, $$\mathbf{\hat{n}}$$, so as to ensure “minimal rotation”.

param crv_ini

Cartesian rotation vector, $$\vec{\psi}$$

type crv_ini

returns

modified and bounded, equivalent Cartesian rotation vector
