Solve 2d wave equation with Finite difference method有限差分法解二维波动方程(Solve 2d wave equation with Finite difference method)

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。画图(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. Paint)

在混沌研究中，求系统整体LE指数的matlab源代码(In the study of chaos, seeking overall system LE index matlab source code)

说明：  matlab写的运动检测 自动实现 十分有用的代码 值得学习！(Motion detection matlab automatically write the code should be very useful to learn!)

永磁同步发电机风力发电通用模型，matlab仿真 (Permanent magnet synchronous generator wind generic model, matlab simulation)
