IDL Routine : Euler Angles to Rotation MatrixJonathan Gagné
When using the rotation matrix, premultiply it with the coordinates to be rotated (as opposed to postmultiplying). The default order for Euler angle rotations is "ZYX". example rotm = eul2rotm(eul,sequence) converts Euler angles to a rotation matrix, rotm. The Euler angles are specified...

Euler angles are a method of determining the rotation of a body in a given coordinate frame. They can be defined as three rotations relative to the three major axes. Euler angles are most commonly represented as phi for x-axis rotation, theta for y-axis rotation and psi for z-axis rotati...

A rotation matrix (used to pre-multiply column vectors) can be used to represent a sequence of intrinsic rotations, for example the extrinsic rotations x−y′−z″ with angles α,β,γ are represented as a multiplication of the following rotation matrices R=X(α)Y(β)Z(γ) Where X(...
The Euler angles are three angles introduced by Leonhard Euler to describe -> the orientation of a rigid body or -> the orientation of a frame of reference (a coordinate system or basis) relative to another. To describe such an orientation in 3-dimensional Euclidean space three parameters are...
