利用MATLAB开发软件进行编程，实现了数字FIR低通滤波器的功能，程序直接可以运行！(Use MATLAB to develop software for programming, implementation of digital FIR low-pass filter function, the program can run directly!)

说明：  在命令窗输入如下内容就得到图形了: [t,x]=ode45( godhua ,[0,10],[0,0,0,1]) subplot(131) plot(t,x(:,4)) xlabel( t ) ylabel( y ) subplot(132) plot(t,x(:,1)) xlabel( t ) ylabel( v ) subplot(133) plot(t,x(:,2)) xlabel( t ) ylabel( \theta ) (At the command window type the following content to be the graphics: [t, x] = ode45 (godhua, [0,10], [0,0,0,1]) subplot (131) plot (t, x (:, 4 )) xlabel (t) ylabel (y) subplot (132) plot (t, x (:, 1)) xlabel (t) ylabel (v) subplot (133) plot (t, x (:, 2)) xlabel ( t) ylabel (heta))

说明：  基于MATLAB求当前坐标系下由线组成的图形的周长(MATLAB-based coordinate system for the current composition of the line the perimeter of the graphics)

说明：  本人实际工作中自己编写的激光谐振器分析程序，在MATLAB中输入main即可运行程序(I actually work in their preparation of the laser resonator analysis program, type in the MATLAB main program can be run)

此为遗传算法的工具书，有很多值得借鉴的例子哦(This genetic algorithm tool, there is a lot to learn from the example )
