WebAug 11, 2024 · 我问过这个问题 fsolve 对任何方程组都适用吗?，我从中得到了满意的答复.我在那里展示的系统x = A * exp (x+y)y = 4 * exp (x+y)，只是一个玩具模型，与我的真实案例问题相似，fsolve 完成了工作(下面的答案中的代码):from scipy.optimize import fsolv WebYou should see that they intersect somewhere between 0.9 and 1.0. Try computing the intersection point using either fsolve or newton in scipy.optimize. Set up a multivariable system and using fsolve to compute an intersection of the two ellipses $$ \begin{align} 4 x^2 + y^2 &= 1\\ x^2 + 9 y^2 &= 1 \end{align} $$
