matlab环境下利用中值滤波函数对黑色图像的还原处理(Matlab environment using median filtering function reduction treatment on black image)

无人系统自助航路规划及自助避碰程序仿真算法发。(Unmanned systems and self-service buffet collision avoidance route planning program simulation algorithm hair.)

这个程序是猫捉老鼠的程序，很不错，是我亲自编写的，好了不说了够20个字了(Cat catch the mouse!)

這是一個讓原始音訊可以再不改變音訊長度下，改變pitch的程式，因為如果音訊用resample，雖然可改變其音訊頻率音高，但是卻會有拉長音訊的副作用，因此設計了一個可以改善其缺點的小方法(實做paper ）(This is an original audio so that you can no longer change the audio down the length of the program to change the pitch because if the audio with resample, although it can change the pitch of the audio frequency, but the audio will be stretched side effects, and thus can improve the design of a small way shortcomings (real do paper))

isodata 迭代自组织的数据分析，用于时频分析算法，包含优化类的几个简单示例程序。( Isodata iterative self-organizing data analysis, For time-frequency analysis algorithm, Optimization class contains several simple sample programs.)

汽车14自由度仿真simulink文件，包括车身6个自由度，悬架4自由度，车轮4自由度。模型跑得通，且和carsim中同种工况下的运行结果相同，精度较高。 除此之外还有模型搭建的对应论文可供参考学习(Vehicle 14 DOF simulation Simulink file, including 6 DOF of body, 4 DOF of suspension and 4 DOF of wheel. The model runs well and has the same result as that of Carsim under the same working condition, with high accuracy. In addition, there are corresponding papers on model building for reference.)

[原创]自己写的mallat算法matlab源程序，完全按照教材定义编写，有助于深入理解mallat小波变换。([Original] wrote it myself Mallat algorithm matlab source code, in full accordance with the definition of the preparation of teaching materials, contribute to better understanding of Mallat wavelet transform.)

EasyMod is a MatLab/Scilab toolbox for teaching modal analysis. It provides a set of functions allowing to establish the identification of modal parameters and these validation. Nowadays, circle-fit, line-fit and least square complex exponential methods are implemented. In addition, some relevant functions are offered in order to complete a modal analysis: operations on the frequency response function (FRF) , generation of FRF from mass, damping and stiffness matrices, MAC (modal assurance criterion) and modal collinearity
