this code is an example for kalman filter

a five level h bridge inverter with gto switches can produce five levels of output harmonics will be very less compaerd with normal inverter

Minimax Approximation and Remez Algorithm

有CDF三角函数曲线/三维曲线图，插值与拟合的matlab实现，部分实现了追踪测速迭代松弛算法。( There CDF trigonometric curve/3D graphs, Interpolation and fitting matlab implementation, Partially achieved tracking speed iterative relaxation algorithm.)

四元数的隆戈库塔法，利用隆戈库塔队四元数进行更新，可以从中提取出载体姿态信息(Quaternion Longo Kutta method, using Longo Coulthard team quaternion update, can be extracted from vector-profile information)

潮流程序，多初学入门者很好使，，分了多个模块，每个模块均有说明 (Trend of the program, more than the novice beginners to very good make, and divided into multiple modules, each module has a description of)

选择输入信号的参数，以及抽样因子，以及采样参数，对信号分别进行上抽样和下抽样，方便非均匀采样的进行。(Select the input signal parameters, and sampling factors, as well as sampling parameters, respectively, on the signal sampling and down sampling, to facilitate the conduct of non-uniform sampling.)

程序尚不完善，固定提取了3个主成分，没有做寻求最佳主成分个数；没有做交叉有效性检验 (good)

chomsky文法判断，0，1，2，3四种文法类型的判断(chomsky)

说明：  2D的FDTD程序，有关边界的设定，物理参数的设定等，对学习FDTD很有帮助。(2D of the FDTD program, setting the boundaries, the physical parameters of the set and so helpful in learning FDTD.)
