ROOTS 的输入不能包含 NaN 或 Inf。 你好,我是用matlab function实现大致如下的功能代码,运行后报错:ROOTS 的输入不能包含 NaN 或 Inf。请问有没有什么解决方法,谢谢! function[Pa1,Pa2]=Blend(pa) F=AeroFun; n=pa.m2/pa.m1; Cp1=pa.gamma1*pa.R1/(pa.gamma1-1); Cp2=pa.gamma2*pa.R2/(pa.g...
This MATLAB function returns the roots of the polynomial represented by the coefficients in p as a column vector r.
0 링크 번역 Hi@cagri sarac If it is already in the transfer function form, then you can use thepole()function to find the roots of the denominator. https://www.mathworks.com/help/control/ref/lti.pole.html There are some examples in the link. ...
You can verify that the function value atais close to zero by entering humps(a) ans = 8.8818e-16 Using a Starting Point Suppose you do not know two points at which the function values ofhumpsdiffer in sign. In that case, you can choose a scalarx0as the starting point forfzero.fzero...
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...

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...
Therootsfunction considerspto be a vector withn+1elements representing thenth degree characteristic polynomial of ann-by-nmatrix,A. The roots of the polynomial are calculated by computing the eigenvalues of the companion matrix,A. A = diag(ones(n-1,1),-1); A(1,:) = -p(2:n+1)./p...
By convention, MATLAB® returns the roots in a column vector. The poly function converts the roots back to polynomial coefficients. When operating on vectors, poly and roots are inverse functions, such that poly(roots(p)) returns p (up to roundoff error, ordering, and scaling). p2 = po...
I am looking at the equation root in the equation root of the root. I have looked at some examples and found nothing much. So how do I find roots? I have tried doing this with the formula function and no luck. I am using Matlab and I really need to use MatLab to find roots as ...
