3D方式演示欧拉角 通过鼠标就可以更改欧拉角的方位，其中代码适用于欧拉角方向余弦矩阵的转换。(findEulerAngs generates Euler angle sets and animates rotations in response to user manipulation of a 3D rigid body (a box). Use the mouse to change the orientation of the box. A wireframe of the original box position will appear. The Euler Axis button animates the rotation about the Euler Axis between the original and new box positions. The Rotate button calculates a set of Euler angles for the rotation type currently selected ( Body or Space ) and the axis set selected in the dropdown menu to orient the axes to the new box position. Derotate reverses this process and brings the axes back to their previous position. Once the axes have been rotated, subsequent rotations are calculated from this new orientation. This means that Space rotations use the coordinate system associated with the previous cube orientation (i.e. the axes of the wireframe cube). Axes DCM is the direction cosine matrix of the current axes orientation in the unrotated inertial frame. Box DCM (in)

帝王蝶优化算法,一种新的元启发式优化算法！(In nature, the eastern North American monarch population is known for its southward migration during the late summer/autumn the northern United States and southern Canada to Mexico, covering thousands of miles. By simplifying and idealizing the migration of monarch butterflies, a new kind of nature-inspired metaheuristic algorithm, called Monarch Butterfly Optimization (MBO), a first of its kind, is proposed in this paper. In MBO, all the monarch butterfly individuals are located in two distinct lands viz. Southern Canada & northern United States (Land 1) and Mexico (Land 2). Accordingly, the positions of the monarch butterflies are updated in two ways. Firstly, the offsprings are generated (position updating) by migration operator, which can be adjusted by the migration ratio. It is followed by tuning the positions for other butterflies by means of butterfly adjusting operator. In order to keep the population unchanged and minimize fitness uations, the sum of the newly-generated but)
