From Rotation and Matrix
A rotation matrix is a 3x3 matrix, which can be used to rotate a coordinate system, notably the direction cosines in MVDirection .
A RotMatrix can be constructed by the default constructor (which will set the diagonal to 1), a copy constructor, and from a set of Euler angles with RotMatrix(Euler)
.
Multiplication can be done (by *= and *) of two rotation matrices.
The (uInt, uInt) operator returns the indicated element.
See Euler
To use in nutation and other coordinate calculations
