You have 3 independent variables and 1 dependent variable. You will need a 4D plot. Unfortunately: there are no symbolic 4d plotting routines with the work-arounds needed to represent 4d, you willnotbe able to get the general shape of the curve. ...
So I have a function f of a symbolic variable let's say x , and I would like to plot my function versus 1/x. How can I do that ? This is an example of my code, I'd like to plot E_norm versu 1/b. symsb;% 1/T
1、Calculate the derivative of a symbolic function: y=4x^{5} (计算符号函数的导数) 示例代码: syms x y = 4 * x ^ 5; yprime = diff(y) 输出结果: 2、练习 (1) f(x)=\frac{e^{x^{2}}}{x^{3}-x+3},\frac{df}{dx}=? (2) g(x)=\frac{x^{2}+xy-1}{y^{3}+x+3},\...

在 MATLAB 中,符号工具箱(Symbolic Math Toolbox)允许用户进行符号计算,包括符号表达式的创建、简化、积分、微分和求解方程等。本文将介绍如何在 MATLAB 中使用符号函数。 2. 定义符号变量 在使用符号函数之前,首先需要定义符号变量。这可以通过 syms 命令来实现。例如: syms x y z; % 定义符号变量 x, y 和 z...
①——plot x=-10:0.1:10;y1=3*x.^4+x.^2-1;plot(x,y1,'r')%x是向量,所以计算一定要表示成点乘 ②——fplot %函数functiony2=draw2(x)y2=sin(x)+x;end%在命令行输入fplot(@draw2,[-5,5]) ③——ezplot y3='x.^2*exp(-x.^2)';ezplot(y3) ...
这个函数在 symbolic 包当中,需要手动安装我们可以直接将数组当做一个多项式使用。通过将两个数组补充为相同长度,就可以通过数组加减进行多项式加减;还可以做乘法p = conv(p1, p2) 返回相乘后得到的数组;以及带余除法[p, r] = deconv(p1, p2) 返回商数组和余数数组;也可以进行积分和求导,同样返回结果数组...
