这是一个100个MATLAB 实例程序，也是从网上搜索到的，对大家有用才好。(This is a 100 MATLAB Examples of procedures, but also from the Internet to search for useful everyone to do.)

Photovoltaic (PV) or solar energy is expected to be one of the most important

在Juan Cardelino发布的FMM(fast marching methos)2维程序基础上改写的3维程序。并改写成适合复杂速度模型，可用于地震旅行时计算。大模型3d算法在matlab下计算速度较慢，根据源码中的注释很容易改写成c程序。(3D FMM program revised from Juan Cardelino s 2D version. The program can calculate the seismic traveltimes in 3D complex model)

说明：  光伏并网逆变器，阳光电源，测试部设计,有待修改 (pv grid inverter,sungrow,test dept desigen)

DiscreteTFDs is a time-frequency analysis package.

Locally-Linear Embedding (LLE)[9] was presented at approximately the same time as Isomap. It has several advantages over Isomap, including faster optimization when implemented to take advantage of sparse matrix algorithms, and better results with many problems. LLE also begins by finding a set of the nearest neighbors of each point. It then computes a set of weights for each point that best describe the point as a linear combination of its neighbors. Finally, it uses an eigenvector-based optimization technique to find the low-dimensional embedding of points, such that each point is still described with the same linear combination of its neighbors. LLE tends to handle non-uniform sample densities poorly because there is no fixed unit to prevent the weights from drifting as various regions differ in sample densities. LLE has no internal model.
