it is a xyz file of a ball and hoop that i wrote using matlab

球体重磁异常剖面，通过球体密度和深度可求的异常剖面的程序-the abnormal profile of ball underground

小球的抛物线轨迹。将轨迹分解成x坐标和y坐标，计算出每一个时刻的x和y值，然后对x和y进行成像就可以得到轨迹了-Parabolic trajectory of the ball. The track is decomposed into x and y coordinates, x and y values calculated each time, then x and y can be imaged on a trajectory
