IMFCC

harmonic mean & geometric mean

This Program simulates the MVDR beamformer which is useful for beginners.

对Lorenz系统进行仿真出李雅普诺夫指数和最大李雅普诺夫指数；可以直接套用到其他的混沌系统进行反正出图即可。(The Lyapunov exponent and the largest Lyapunov exponent are simulated on the Lorenz system, and the other chaotic systems can be directly applied to the inverse diagram.)

简单实现基本的lstm功能，可以运行，如有不足还请指正(Simple implementation of the basic LSTM function, you can run, if there is insufficient, please correct)

利用matlab自带的eig函数,对带非值二维场的eof分析(Using eig function in Matlab, eof for the two-dimensional field with some non-value data )

利用singer模型实现对机动目标的跟踪(the maneuvering target tracking by using singer model)

四节点等参元的matlab程序，可用于平面单元的有限元计算(four_node_quadrilateral_isoparametric_element matlabcode)

用matlab实现二次曲面图绘制，用来绘制曲线图(Draw a graph quadric)

室内定位时差定位算法。包括 chan算法，fang算法。功能是实现室内定位。在3到7个接收基站的基础上，获得较高精度的定位(Indoor location TDOA location algorithm. Including Chan algorithm and Fang algorithm. Function is to achieve indoor positioning. On the basis of 3 to 7 receiving base stations, high precision positioning can be achieved.)

说明：  本程序产生一个智能天线系统的信道模型，每一条多径都服从瑞利衰落。(This procedure generates a smart antenna system channel model, are subject to each multipath Rayleigh fading.)
