About Simulink
Simulink is a software package for modeling, simulating, and analyzing dynamic systems. It supports linear and nonlinear systems, modeled in continuous time, sampled time, or a hybrid of the two. Systems can also be multirate, i.e., have different parts that are sampled or updated at different rates.
Simulink encourages you to try things out. You can easily build models from scratch, or take an existing model and add to it. Simulations are interactive, so you can change parameters on the fly and immediately see what happens. You have instant access to all the analysis tools in MATLAB®, so you can take the results and analyze and visualize them. A goal of Simulink is to give you a sense of the fun of modeling and simulation, through an environment that encourages you to pose a question, model it, and see what happens.
With Simulink, you can move beyond idealized linear models to explore more realistic nonlinear models, factoring in friction, air resistance, gear slippage, hard stops, and the other things that describe real-world phenomena. Simulink turns your computer into a lab for modeling and analyzing systems that simply wouldn't be possible or practical otherwise, whether the behavior of an automotive clutch system, the flutter of an airplane wing, the dynamics of a predator-prey model, or the effect of the monetary supply on the economy.
Simulink is also practical. With thousands of engineers around the world using it to model and solve real problems, knowledge of this tool will serve you well throughout your professional career.
For modeling, Simulink provides a graphical user interface (GUI) for building models as block diagrams, using click-and-drag mouse operations. With this interface, you can draw the models just as you would with pencil and paper (or as most textbooks depict them). This is a far cry from previous simulation packages that require you to formulate differential equations and difference equations in a language or program. Simulink includes a comprehensive block library of sinks, sources, linear and nonlinear components, and connectors. You can also customize and create your own blocks. For information on creating your own blocks, see the separate Writing S-Functions guide.
请大哥大姐帮忙翻译一下MATLAB的帮助
Simulink 鼓励您尝试事。您能容易地建立模型从头, 或采取一个现有的模型和增加来它。模仿是交互式的, 因此您能正在进行中改变参量和立刻看什么发生。您得以进入对所有分析工具的立即在MATLAB., 因此您能采取结果和分析和形象化他们。Simulink 的目标是给您塑造和模仿乐趣的感觉, 通过鼓励您提出问题, 塑造...
【求助】matlab,maple,Mathematica哪个更好些?
Matlab有大量的现成的库可以使用,在很多方面都有非常广泛的应用,很有针对性的,非常强大。类似于C#中提供很多现成的类。maple在符号运算和数值计算中都有很好的表现,但是库没有matlab多。如果你是搞什么专业性的东西,还是matlab
MATLAB 不同方法解一元方程
解法1:solve('x^2-10') %用于一般的方程,也包括指数、余弦等复杂方程 解法2:roots([1 0 -10]) %用于多项式方程 解法3:fzero采用零点,是极限的求法 f=@(x) x^2-10;y3_1=fzero(f,[0,5]),y3_2=fzero(f,[-5,0])...
急需matlab知道两组数据怎么求出它们之间的规律然后拟合成曲线?我刚接...
norm(feval(fun,c,x)-y)^2%残差平方和 lsqcurvefit可以作为各种类型曲线的拟合,最小二乘法能找到符合经验公式的最优曲线,但是这一经验公式是否有效还需要事后检验.一般可以从图像上作 出判断,定量方法是计算残差平方和,再进行统计检验.
MATLAB中有没有求余运算符?
有,matlab是经常使用的运算工具。 在编程中,经常遇到求余的问题。mod和rem是常用的两个命令。rem(m,n); m除以n所得余数。rem(x,y)命令值是:x-n.*y,如果y不等于0,其中的n = fix(x.\/y)。这里之所以用点数,是因为如果m和n是向量的时候也是可以运算的。rem(m,n); m除以n所得余数。
matlab绘制直方图?
举个例子 A=imread('cameraman.tif');hist(A(:),0:255);xlim([0,255]);hist是将数据做出频数图的命令 这里A就是一个图像矩阵。 你可以用imshow(A)查看该图像。'cameraman.tif'在matlab中自带。A(:)是将A写成一列(否则hist会分别对每一列进行统计)0:255就是分组。hist会将其分成256个组...

clock_t是一个长整形数。在time.h文件中,还定义了一个常量CLOCKS_PER_SEC,它用来表示一秒钟会有多少个时钟计时单元,其定义如下:define CLOCKS_PER_SEC ((clock_t)1000)在MSDN中,查得对clock函数定义如下:clock_t clock(void) ;这个函数返回从“开启这个程序进程”到“程序中调用clock()函数”...

用matlab画函数图:y=e^jwt
f=50;R=50;c=3*10^8;w=2*pi*f;t=0:0.01:100;ft=exp(j*w*t);gt=f*(t-2*R\/c);plot(t,ft)figure;plot(t,gt)
matlab m_map m_ll2xy 出现错误nan
变量m_map m_ll2xy 出现错误nan的原因是,赋值给m_map,m_ll2xy 的计算式中的分母为零。即 A\/0=NaN(无意义的数)。
