signal_analyzer
说明: 最近看到有人提问怎样用FFT实现频谱分析,我认为能够进行到频谱分析的人,对于系统研究的深度基本上已经相当不错了。本人今天做了一个例程,发给大家参考一下。
历程主要内容(signal_analyzer.rar)如下:
test1.txt 第一列为时间t,0.001s为步长;第二列为系统的输入信号;第三列为系统的输出信号。
signal_analyzer.m首先将test1.txt 的数据读入workspace,然后进行FFT,分析出两信号的频率,输出对于输入的幅值衰减(db),输出对输入的相位差。(The question was asked recently to see the realization of how to use FFT spectral analysis, I think that spectral analysis can be carried out to those who study the depth of the system basically is already quite good. Today I made a routine, distributed to Members for reference. The main contents of the course (signal_analyzer.rar) are as follows: test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as a system output signal. signal_analyzer.m first test1.txt data read into workspace, and then proceed to FFT, analysis of the two signal frequency, output amplitude for input attenuation (db), the output of the input phase difference.)

fit
Matlab中提供了一种快速实现多项式拟合的方法函数polyfit()函数,
其格式:p=polyfit(x,y,n)其中x,y为样本向量,n为拟合的多项式的项数。下面拟f(x)=sinx+x,在区间【-3,3】上以0.5为间隔进行拟合。(Matlab provides a fast way to achieve polynomial fitting function polyfit () function,
The format: p = polyfit (x, y, n) where x, y as the sample vector, n is the number of items of polynomial fitting. The following proposed f (x) = sinx+ x, the interval-3,3】 【intervals on the order of 0.5 to fit.)

Filter_Bank_Design
完全重构以及近似完全重构滤波器组设计程序。
(The goal is to design M analysis and synthesis FIR filters so that the analysis filters satisfy some frequency specifications and the filter bank(almost) meets the perfect reconstruction (PR) conditions.
The algorithm can design both uniform (critically/over sampled) and non-uniform filter banks.)

stewart_matlab codes
说明: Stewart平台是典型的并联机器人的代表,相比于串联机器人来说,其多链式闭环的结构让并联机器人的运动学求解变得复杂。该程序内有Stewart平台研究的一整套程序,包括:运动学逆解、正解、工作空间和动力学的matlab程序,可以减少你的工作量。(Stewart platform is a typical representative of parallel robot. Compared with serial robot, its multi chain closed-loop structure makes the kinematics solution of parallel robot more complex. The program contains a complete set of Stewart platform research procedures, including: inverse kinematics, forward kinematics, workspace and dynamics matlab program, can reduce your workload.)

说明: 基于灰色预测,指数平滑预测的几个MATLAB程序,对于预测类问题的数学建模,可以说是必备程序。我的导师给我传的。
funesm1,2,3分别为一二三次指数平滑预测程序
fungry为灰色预测程序
funcoef为时间序列预测程序
pudn为广大的编程爱好者提供了一个交流的平台,我在此先谢谢网站的工作人员,我也会努力编出好的程序,一起同大家分享。(Based on Gray predicted that the number of exponential smoothing forecasts MATLAB procedures, issues for the prediction of the mathematical modeling, can be said to be an essential procedure. My mentor gave me spread. funesm1, 2,3 were 123 times procedures fungry exponential smoothing forecast procedures funcoef gray prediction for time series forecasting procedures for pudn programming for the majority of fans provided a platform for exchange, I would like to thank the site staff, I will strive for a good program, to share together.)

ROI_detector
This is an implementation of the algorithm described in our paper [1]. The input is any map generated by saliency detection algorithms like Itti-Koch [2] or GBVS [3]. The algorithm outputs a binary mask without requiring a threshold for the saliency map. More details about it are described in our paper.
