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...

solve('x-5') 1. MATLAB将执行上面的语句,并返回以下结果: ans = 5 1. 2. 然而,如果公式涉及多个符号,那么MATLAB默认情况下,假定正在解决x,解决命令具有另一种形式: solve(equation, variable) 1. 在那里,还可以提到的变量。 例如,让我们来解决方程 v – u – 3t2 = 0, 或v在这种情况下,我们应该这...

I am new to Matlab, and I would like to solve an equation: The code I wrote is: 테마복사 syms x; eqn=(sqrt(1+(0.018/x))-sqrt(0.018/x))/(sqrt(1+(0.06/x)-sqrt(0.06/x))==1.12446); solx=solve(eqn,x); But when I put the answer back to the equation, it cannot gi...

sol = solve(eq, x); ``` In this case, the "syms x" command declares a symbolic variable x so that Matlab can solve the equation symbolically. The "eq" variable represents the equation we want to solve, and the "sol" variable stores the solution. For a system of equations involving ...
