The following sections contain two examples that illustrate how to find a zero of a function using a starting interval and a starting point. The examples use the functionhumps.m, which is provided with MATLAB®. The following figure shows the graph ofhumps. ...
f1 = matlabFunction(sol_d(1)); f2 = matlabFunction(sol_d(2)); Mx = 4; b = 2; tf = 4; tw = 20; d1 = f1(Mx,b,tf,tw) d2 = f2(Mx,b,tf,tw) 댓글 수: 1 Walter Roberson2022년 3월 11일 After that you can subs() a vector of Mx values into sol_d to get...
Use thefzerofunction to find the roots of nonlinear equations. While therootsfunction works only with polynomials, thefzerofunction is more broadly applicable to different types of equations. 在MATLAB命令窗口中输入:doc fzero 查看fzero的相关介绍。

This MATLAB function returns the roots of the polynomial represented by the coefficients in p as a column vector r.
functionY=Y(x) %variables a=1; y=2; b=2; c=3; Y=a*x+b*y+c*xy; end I can use the command: ThemeCopy iftrue fzero(@Y,2) end to find the root of this equation. and it works, however my question is how to write a loop to solve this equation for varying ...
func = matlabFunction(f, 'Vars',{[x(1), x(2)]}); 然后调用fsolve对于函数func进行求解,输出一个求解消息和解solution: 1 2 3 4 5 6 7 8 9 % 命令行输入 solution = fsolve(func, [0,0]) % 命令行输出 Equation solved. fsolve completed because the vector of function values is near zero...
To find the roots of a spline,fnzerosfirst converts the spline to B-form. The function then performs some preprocessing to handle discontinuities and then uses the algorithm of[1]. References [1] Mørken, Knut, and Martin Reimers. "An unconditionally convergent method for computing zeros of...
The accuracy of higher-order LP roots has been improved using the variable precision integer (VPI) format in MATLAB. MATLAB's 'roots' function and VPI method are also compared.doi:10.1007/978-81-322-1157-0_17D. JatinA. E.,I.I.Sc...
