Web你可以使用与标量版本中相同的循环。只需要注意行和列。如果像以前一样，结果被格式化为列列表，现在是y_num = zeros(2,n+1)，那么你需要将整个列作为状态向量寻址，否则你只是在其他地方得到一个数据位置，. y_num(:, i + 1) = y_num(:, i) + (h * f(t(i), y_num(:, i))); WebSolving a boundary value problem using bvp_solver is done in two parts: First, defining the problem, creating a ProblemDefinition object and second, solving it, creating a Solution object which can be called to evaluate the solution at points within the boundaries. At its simplest this works like this:

Web15 Feb 2013 · The reason we cannot use an initial value solver for a BVP is that there is not enough information at the initial value to start. In the shooting method, we take the function value at the initial point, and guess what the function derivatives are so that we can do an integration. ... import numpy as np from scipy.integrate import odeint from ...
