LTSA[19] is based on the intuition that when a manifold is correctly unfolded, all of the tangent hyperplanes to the manifold will become aligned. It begins by computing the k-nearest neighbors of every point. It computes the tangent space at every point by computing the d-first principal components in each local neighborhood. It then optimizes to find an embedding that aligns the tangent spaces.

2维曲面拟合，gauss or gabor 函数(Functions to fit a 2D Gaussian or 2D Gabor to a surface. The routines are automatic in the sense that they do not require the specification of starting guesses for the model parameters. This is done by evaluating the quality of fit (sum of squared error) for many different choices of parameters then refining the most promising set of params through least-squares (exhaustive search followed by refinement). Least-squares is statistically equivalent to maximum likelihood estimation of the model parameters on the assumption of independent, normally distributed Gaussian noise in the observations (pixels). autoGaussianSurf(xi,yi,zi) fits a Gaussian,)

应用蒙特卡罗模拟方法计算期权价格 统计模拟方法亦称蒙特卡罗(Monte-Carlo)方法.因为通常的教科书几乎不涉及 此内容.了解的人不多。听到过的人又常把它看作是统计力学或核物理等学科的专门工具.很少想到这个方法与自己的科研工作有什么关系。 (Application of Monte Carlo simulation method of calculating the option price statistics, also known as Monte Carlo simulation method (Monte-Carlo) methods. Because textbooks are usually almost do not involve this content. Not many people understand. Heard of people often see it as a statistical mechanics or nuclear physics disciplines, such as specialized tools. Rarely thought about this method and their own research work has anything to do.)

说明：  Matlab细化算法，重要参考资料，细化效果较好。(Matlab thinning algorithm, an important reference materials, refinement is better.)
