地球物理勘探中重力资料解释的主要目的是由地表观测值推断地下可能存在的密度分布。众所周知,任何一组重力数据都可能由无数个密度分布所引起。即使假设了重力异常是由具有均匀密度差的单一地质体产生的,也得不出唯一的解(Gravity geophysical exploration data interpretation main purpose is inferred from surface observations may exist underground density distribution. Is known, any set of data may be provided by gravity density caused numerous. Even assuming that the gravity anomaly is determined by having a uniform density difference arising from a single geological body, they have no unique solution)

使用pid方法控制单级倒立摆，解压后把两个文件放在同一个文件夹里双击nn_pid.m就行了(Pid way to control the use of single-stage inverted pendulum, after extracting the two files in one folder double-click on the list nn_pid.m)

偏微分方程的MATLAB解法，能快速求解，阐述了其编程思想，很实用(Solution partial differential equations )

用经典的BJ方法估计ARMA模型，一个经典范例(Using the classical BJ approach to estimate ARMA models, here is an example)
