基于matlab的彩色图像转成灰度图像，然后进行图像旋转并画布扩大，最后进行均值插值(Matlab-based color image into gray image, and then expand the image rotation and canvas, and finally to mean interpolation)

Function to calculate the principal curvatures on a triangular mesh. Approximations of curvature are based on local (N=1) neighborhood elements and vertices. Note: Directions of curvatures aren t calculated appropriately. Will post an updated version once this is implemented. Note that calculations at vertices with few adjacent triangles, and hence few adjacent vertices, are expanded to a greater neighborhood.

通过ifft变换，实现美国六级轨道谱的不平顺时间域信号模拟( the simulation of track irregularity based on the ifft transform )

该程序可以画出三维的运动轨迹，可以看到轨迹的前视图，还可以对轨迹进行旋转等(The program can draw three-dimensional trajectory, you can see the front view of the track, the track can also be rotated, etc.)
