Duffing-equation

此算法描写了如何在计算机上表达迎风方案，注意怎样表示差分。(This algorithm describes how the expression of the wind on the computer program, pay attention to how that difference.)

说明：  是有关机器学习中讲密度估计的好资料，自己找了很久才找到的，国外人写的很容易懂，乐意分享(Machine learning is related to good information about density estimation, for a long time to find your own, and foreign people to write easy to understand, are willing to share)

DESCRIPTION: This Matlab algorithm performs many tasks associated with power system analysis. First, it has the ability to perform both fully coupled and dc power flow analysis. Second, it has the ability to create measurements (with user-defined error) to be used as input for state estimation. Third, it has the ability to perform state estimation - allowing the user to examine how the placement of measurement devices as well as magnitude of distibution of measurement error affect the discrepency between power flow and state estimation results. In essence, it provides the user with a complete package for the study of both power flow and state estimation in n-bus power systems.
