走向无限延深有限的无限长薄板状体在matlab上实现Za,Ha,T的异常曲线。(The abnormal curves of Za, Ha and T are realized on MATLAB for an infinite thin plate with infinite extension and finite length.)

计算不同年（年限可以自己调整）等额本息还款方式下的每月还款本金与利息(Calculate the monthly repayment principal and interest under the equal principal and interest repayment method for 30 years (years can be adjusted by oneself)

通过计算方差，确定划分坐标轴，最后，将点云划分到一个个格子中，这样的好处在于可以将噪点和有效点分别存储于不同的格子中，方便进行去噪。(k-d tree create;By calculating the variance, the coordinate axis is determined. Finally, the point cloud is divided into a number of lattices. The advantage is that the noise and the effective points can be stored in the different lattice, so that the noise can be de-noised conveniently.)
