图像的小波分解

输入高频信号，设计高通滤波器，程序中有图像显示()

这是超声波测距的原理图及PCB图，做出来了哦(This is the Ultrasonic Ranging and PCB schematic diagram, do it, oh)

Fisher是多元统计分析的常用的方法之一，判别分析方法可在各种领域得到应用。一般用于确定属于一个可观测量是什么类型。(Fisher method is one of the common methods of multivariate statistical analysis, discriminant analysis method can be applied in various fields. Usually used to determine what type of a observables belonging.)

完整代码，可以运行，有数据，解四元数采用的是双子样法，地球参考系用的的是椭球体模型，还有kalman滤波，推荐给初学惯导的同志

对于初学者具有参考意义，滤波求和方式实现宽带波束形成，一种流形学习算法（很好用），一种噪声辅助数据分析方法,Matlab实现界面友好，最终的权值矩阵就是滤波器的系数。

说明：  主要用于潮流计算，可以设置多平衡节点fgfgfgfg(yhuhgfjhgjhgjhg)

四旋翼飞行器在MATLAB下的建模程序，非常好，非常真实(Four-rotor aircraft under the MATLAB modeling program, very good, very durable)

MATLAB源码，preprocessing.m: preprocess the picture including:Wiener filter; meddle value filter, change a gray picture to a binary one and then get the skeleton. centralizing.m: input the source picture output the core point of the fingerprint. samfun.m: generate the sample pattern automatically, which is used to sample the fingerprint. gabor2d_sub: get gabor filter. varpic.m: calculate variance picture(MATLAB source, preprocessing.m : preprocess the picture including : Wiener filter; meddle value filter, change a gray picture to a binary one and then get the skeleton. centralizing.m : input the source picture output the core point o f the fingerprint. samfun.m : generate the sample pattern automatically, which is used to sample the fingerprint. gabor2 d_sub : get gabor filter. varpic.m : calculate variance picture)

this program takes the data from an IMU as the input and calculates the body s trajectory ,velocity and attitude . it plots the velocities and euler angles vs time and the body s trajectory
