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)

说明：  通用NSGA2程序，里面有详细的注释，亲测可用(General NSGA2 program, which has detailed notes, pro test available)

hotelling transformation has been written with help of Matlab 2007a. This technology has been applied to transform images. A test image has been included in the file for explanation. It accpets 256 color map bmp image as input and produces the output.
