[Other] 3dtrans DL : 0: 3D Space Coordinate Transformations This folder contains 3 files (m-functions) : - t2x.m Transformation Matrix to Generalized Position Vector. - x2t.m Generalized Position Vector to Transformation Matrix. - m2m.m Mass/Inertia Tensor transformation with coordinate change. In the Generalized Position Vector the orientation can be expressed with: - unit quaternion, - Euler angles xyz (roll, pitch, and yaw), - Euler angles zyz (rotation, precession, and mutation), - unit vector and rotation angle, - Denavitt-Hartemberg parameters. Conversion between the above orientation systems can be easily achieved. The three files work independently on each other, but since they work on the same objects it is somewhat useful to keep them in the same folder. - 3D Space Coordinate Transformations This folder contains 3 files (m-functions) : - t2x.m Transformation Matrix to Generalized Position Vector. - x2t.m Generalized Position Vector to Transformation Matrix. - m2m.m Mass/Inertia Tensor transformation with coordinate change.

[matlab] findEulerAngs DL : 0: 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

[Algorithm] EFG2 DL : 0: 无网格法在数值计算中不需要生成网格，而是按照一些任意分布的坐标点构造插值函数离散控制方程，就可方便地模拟各种复杂形状的流场。该法大致可分成两类：一类是以Lagrange方法为基础的粒子法（Particle method），如光滑粒子流体动力学（Smoothed particle hydrodynamics，简称SPH）法，和在其基础上发展的运动粒子半隐式（Moving－particle semi－implicit，简称MPS）法等；另一类是以Euler方法为基础的无格子法（Gridless methods），如无格子Euler/N—S算法（Gridless Euler/Navier-Stokes solution algorithm）和无单元Galerkin法（Element free Galerkin，简称EFG）等。(In the numerical calculation, meshless method does not need to generate grid, but constructs interpolation function discrete control equation according to some arbitrarily distributed coordinate points, which can easily simulate various complex shapes of flow field.)
