卡尔曼滤波仿真，对于初学卡尔曼滤波器的人有很大的帮助(Kalman filter simulation Kalman filter for the beginner who has a lot of help)

功能：该程序用于仿真截断正态概率下舰艇机动加速度均值与方差的关系，输入：舰艇的最大机动加速度，输出：两幅加速度均值与方差的关系图。(Features: The program for the simulation of truncated normal probability of ship maneuvering the relationship between the mean and variance, type: motor ships of the largest acceleration, output: 2 acceleration mean and variance diagram.)

我写的用于绘制绘制矩阵图形的小程序，要求matlab版本在6.0以上。(I write for rendering graphics rendering matrix of small procedures, requirements in Matlab version 6.0 and above.)

说明：  防人智能控制的设计，有给定的传递函数和设计目标，simulink的matlab6.5源代码，修改参数即可用与其他系统.(Anti-human intelligent control design, there are a given transfer function and design objectives, simulink of matlab6.5 source code, modify the parameters can be used with other systems.)

An efficient algorithm for identification of PIL on Solar Dynamic Observatory (SDO) Helioseismic and Magnetic Imager (HMI) magnetograms. Detailed description will appear in the paper: Volobuev, D.M. Polarity-Inversion Line Preceding X-class Flare, Solar Physics, Initial data (65 megabyte .fits magnetograms) can be downloaded from http://hmi.stanford.edu/ - Model_test_PIL_Open.m script - calculates parameters of the example(simulated S-curve) - SDO_PIL_Open.m script - identifies PIL on SDO magnetogram and calculates its parameters - 5 functions are used within these scripts

说明：  信号处理的一点东西，关于褶积，循环褶积，还有一点病态系统的，(matlab signal analysis)

提供两个小程序，一个是多重分形谱算法；另一个是盒子维数的计算。(Provide two small programs, one is multifractal spectrum algorithm the other is the calculation of box dimension.)

说明：  matlab信道模型，对OFDM信道建模，包括普通IDFT算法和IFFT快速算法。(Matlab channel model, the right OFDM Channel modeling, including general IFFT SINGLE algorithm and fast algorithm.)
