The equations in the nonlinear system are e−e−(x1+x2)=x2(1+x21)x1cos(x2)+x2sin(x1)=12. Convert the equations to the form F(x)=0. e−e−(x1+x2)−x2(1+x21)=0x1cos(x2)+x2sin(x1)−12=0. The root2d function
MATLAB Online에서 열기 Is there a way to solve a system of 3 nonlinear equations without symbolic variables? I showed how to solve the equations I need solved below using solve() but is there a way to do it without symbolic variables?

To solve the nonlinear system of equations using the problem-based approach, first define x as a two-element optimization variable. Get x = optimvar('x',2); Create the first equation as an optimization equality expression. Get eq1 = exp(-exp(-(x(1) + x(2))) == x(2)*(1 + ...
Open in MATLAB Online I have a large system of nonlinear equations in matrix form. Somewhat like X*A+X.*X==0; whereXis matrix of unknowns,Ais scalar matrix . I wish to solve it using fsolve, like the simple example shown in documentation of fsolve by using root2d.m fu...

Do you mean get R01 and R02 in one shot, or do you mean find where the two functions meet (what I usually think of when someone says they want to solve a system of equations)?
官方参考页:Solve system of nonlinear equations - MATLAB fsolve fsolve可能是目前matlab的内置库函数中最常用的求(非线性)方程(组)解的函数,也是最为人熟知的。它用于数值求解方程(组),具有较广的适用范围(适用于高维和非线性、非多项式情形),甚至可以求矩阵方程的解(即甚至可以求解未知量为矩阵的情景)。fsolve函...
